So, for example, while the right signal flashes, the left brake light works but the right turn signal isn’t overridden by the brake. If you step on the brake pedal, both the left & right turn-signal outputs will turn on together for the brake lights. These have to be pried away from the base and unhooked in order to remove the flasher, which can be a little tricky. In any case, you'll want to trace what you suspect to be the ground wire from the bulb housing to its termination point, which is the point at which it screws or bolts to the vehicle's chassis. In this post I’ll tell you everything you need to know to make the switch to LEDs, and I’ll also tell you why I opted not to do it, for now. Again, see if they fit. Another consideration is that older lens housings are designed to work with incandescent bulbs, i.e., they’re designed to reflect light from a 360˚ source. The trailer lighting works fine with other vehicles so I'm certain the problem is in my truck. I am sending a link that will show how to wire the load-resistor kit to your lights. The 1156 is the single pole, turn signal bulb, and the 1157 is the dual pole bulb for brake lights. The reason I am looking at this option is because right now when my brake light is on and the turn signal is flashing the brake light drowns out the turn signal and you can not see the turn signal. The manufacturer has designed the double time speed as an indicator. A normal flasher uses resistance in the turn signal circuit to control the flash rate. If your turn signal doesn't light up at all or doesn't flash, it can often be a bad ground connection that's the culprit. Nice to hear your take on it. In most vehicles, the ground wires will be either brown or black. All of the bulbs I ordered were a hair wider than the stock bulbs and wouldn’t fit into the housings. :oops: :oops: That would be confusing and stupid. Turn signals that don't work in one direction or the other may be due to a faulty switch, particularly if the non-working side starts functioning when you use engage the hazard lights. This is especially an issue with the marker lights on some models of ARB bumpers, as the bulbs in the lens housings do not face forward. This concerns me for obvious reasons I want to make it very clear to the car behind me where I am heading and what I plan to do. One note on the Gen 2 Montero turn signal housing. Note the opening for the speaker. Some sites suggest adding a resistor to the circuit but that creates heat and negates the LEDs low-power-draw benefit. So, check your device and look for the cause, accordingly! It can be difficult to create a turn signal system. We are going to assign each wire with a letter for easier reference: Red-A, Green-B, and Black-C. KTPhil wrote: Bruce wrote: VOLKSWAGNUT wrote: maybe I missed it here, but I have yet to see a voltage drop test done. Does anyone know if this column had the brake override switch in it to allow the brake light to flash instead of staying steady on when the turn signal is implemented? Click below for the diagram. I thought it updated the look of the truck and, of course, LEDs use much less power and last practically forever. LED break lights flash when turn signal is activated (motorcycle) Hi everyone, Electricity is my weakness so any help is seriously appreciated. Thanks again for your help and speedy response. I chose to use amber, bullet-type, motorcycle LED turn-signal lights on the front and rear. My Honda ST1100 had beautiful 3-wire turn signals (1157 socket) which meant that the turn signals could function as both 'running lights' and as 'turn signals'. We have changed the bulb but still nothing. 2. If you order it, be sure to get red, 1157 bulbs for the brake lights; amber, 1156 bulbs for the turn signals; and white 1156 bulbs for the reverse lights. Update 5/12/2013: The bulb I found in my search that had the best balance of price and brightness was the Matrix II, a 32 LED bulb that projects light both straight ahead and in 360˚. Since they are both doing it and the brake lights do not work, it … I just wish they weren’t so expensive. You will need one kit for each LED bulb used in your turn signals. White LEDs will appear dimmer in brake and turn signal applications than their color-matched counterparts. The red arrow points at the flasher relay. so do your self a favof and measure the voltage drop across each componnent, the switch (turn and brake) the fuses, in addition to the drops at the tail light. Really, they should be more noticeable than that with the stock spec bulbs in there. My ultimate reason for switching to LED’s was for the lower power draw. turn signals as running lights wiring - Hi guy's, this is my first post, haven't found much help on other sites. If the turn signal still hyper flashes, take the wires out and tap it to another wire and try again. To make sure the problem is isolated to the trailer, I recommend using a simple light tester, like part # 40376, to test the trailer connector on your tow vehicle to make sure it is functioning properly. Any suggestions? In this day of tailgaters i don't want my bug to be the one getting swatted. Is this 6V or 12V? I feel it adds to the danger by directing too much attention to the one vehicle, and not to the surrounding situation, which can lead to bad decisions on slowing, lane changes, etc. I had seen them on my friend Greg’s truck and I liked the crisp on/off quality. This might not seem like a big deal, but on a 2-wheeler where you want to be seen as much as possible, having those running lights can be a huge visibility boost. If you use an LED that projects only in one direction, light will only appear to come from a small part of the turn signal or brake light lenses. The converter you can use is # RM-732. The Matrix II didn’t fit in my truck because they were too wide to fit through the holes in the back of the lens housings. Something is going to be flashing … Replacement LED’s for 1156/1157 bulbs, definitely puts out less light and less spread. To fix this brake light override, we need some mechanism that will detect when a turn signal is ON and that will not allow the brake light to feed that light. On the plus side, LEDs only draw 170mA, whereas an incandescent bulb will draw about 2 Amps. This takes the separate turn and brake signals and makes them a combined circuit. Since LED bulbs have much less resistance, it throws the flasher off causing the turn signals to blink really fast (hyper flashing). If the trailer is one that is pulled by a motorcycle or a trailer designed to carry a motorcycle, you will need a converter in order to convert the wiring system used by the 6-Way to a 2 wire system used by trailer lights. To most drivers, turn signals seem pretty simple: There’s a lever that makes your signal lights flash. Taillights/Marker Lights Not Flashing or Rapid (Hyper) Flashing. The controls can be wired so the brake lights don't sequence if that is what you wanted. It’s an “EBL” type. A coat or two of red sprayed 'inside' the amber lens will only allow the red wavelength your bulb to come through making the lens appear to be red unless the lights are turned off. Switch your amber bulbs to red. Thanks again for your help and speedy response. This concerns me for obvious reasons I want to make it very clear to the car behind me where I am heading and what I plan to do. A few months ago I thought it would be cool to convert my turn signals and brake lights to LEDs. The most expensive, multi-LED bulbs only put out 220 lumens and costs $24.95. I have attached a video that shows how to do this. They add front and black flashing lights that can be seen by anyone without having to shine light on them (like reflectors need). I will refer to this as the "main" unit. A … The brake lights use the same bulbs as the turn signals so the brake lights will sequence once then all the bulbs will stay on until you let off the brakes. It answers my question that the steering column turn signal switch is not designed to override the brake light. It is a dual element bulb. Remove the cable between the truck and the trailer and make sure that the connections are clean and tight. First, check the dimensions of the LED bulbs you’re considering against the openings in the lens housings, through which the bulbs must pass. It answers my question that the steering column turn signal switch is not designed to override the brake light. A standard 1156 incandescent bulb puts out about 400 lumens and costs about $0.50. I'm having a similar issue to the original questioner: The brake and running lights will start flashing when the turn signals/hazards are activated. Unless one of the turn signals is on then one side will continually sequence and the other will stay on. With both brake lights blinking, the hazard light circuit may be crosses in as well. There’s a good chance the bulbs you’ll be replacing are the common 1156 and 1157 types. A new flasher isn’t expensive, no more than $15. I decided to avoid using the brake lights on the UTV, since I really didn’t want to interrupt the existing wiring and end up with a can of worms. If you decide to move ahead and convert to LEDs, you’ll need to replace your turn signal flasher module with one designed specifically for LEDs. But there’s actually some cool technology at … I thought it updated the look of the truck and, of course, LEDs use much less power and last practically forever. The flasher has a pair of plastic hooks by which it snaps into, and holds itself, to its base. This kit will prevent the turn signals from hyper flashing. This is also a good point to check your parking lights, which usually utilize the turn signal bulbs. would just be a matter of switching wires. I am considering making my turn signal bulb brighter with a 756 bulb so it overpowers the brake light when they are both on. The most times you will try to tap the wires is three times. The reason I am looking at this option is because right now when my brake light is on and the turn signal is flashing the brake light drowns out the turn signal and you can not see the turn signal. This is what the flasher in my Montero looks like. The Problem: That has to do with the positioning of the connector pins. (Yeah, I still drive it and I love it!) Does anyone have the wiring diagram for this turn signal switch on the column? Thanks again for your help and speedy response. Even when you encounter a bulb failure in the headlamp then, also the turn signals start blinking fast. Would try the next brighter bulb. If you’ve done this conversion, and want to share your experience, please comment. Thanks, Greg. Here I’m taking off the panel below the steering column. If you need to keep your parking lights, or hazards, on for long periods of time without running the engine, that’s a benefit. Some even work with both incandescent and LED bulbs. I have a 2001 Honda Prelude, and it came with standard 2 wire turn signals up fornt, and standard two wire running lights on the side. From the mid 50's thru 1961, cars which did not have semaphores used the Stop lights to double as the rear Turn indicators. The signals/brake lights use the same bulb. On the plus side it lasts longer, draws less power (good for older vehicles with aging electrical systems) and lights up instantly (the LED brake lights activate something like a 0.2 seconds faster than incandescent – I don’t recall the math, but at 60 MPH, that’s something like 17 feet of travel before fully lit). This concerns me for obvious reasons I want to make it very clear to the car behind me where I am heading and what I plan to do. Faulty Bulb. Even a bulb with multiple LEDs that projects in 360˚, it won’t put out as much light as a standard bulb. Right now I have the standard two bulb system where one bulb is my 1156 single filament turn flasher bulb and the other bulb is my 1157 dual filament with brake and tail/park light. I've replaced the trailer harness and this still doesn't rectify the problem. If you have a vehicle on which the lenses themselves are removable, and the bulbs are installed from the front, instead of through the back, the bulbs will most likely fit. To do that, a special Turn Signal switch with 6 wires instead of the later 3-wire design was used. How can I get my brake light bulb to flash with the turn light bulb? The wires carrying the power supply from the turn signal switch is connected or touching the brake wires. or re wire so turn sig bulbs run as brake lights and brake lights are the turn signals. This video is a guide showing the proper way to wire LED turn signal resistors. Answer: Sounds like you are not getting any voltage to the right side. they should not be dimmed by the brakes. If you look at the multi-function switch schematic the brake lights only get voltage on the white wire #17 through the stop lamp switch when the brake pedal is depressed.But the #17 wire also goes to the multi-function switch and if the switch shorted internally and back feeds voltage on wire #17 with the turn signal activated then the brake lamps would blink with the turn signals.You can test for voltage at the … I’m also not fully convinced on LED’s (although currently installed on the monty). The reason I am looking at this option is because right now when my brake light is on and the turn signal is flashing the brake light drowns out the turn signal and you can not see the turn signal. On my 1995 (Gen 2) Mitsubishi Montero I found that a millimeter or two made a difference. The signal filament is brighter than the parking light filament, so if one light is "extra" bright the bulb may be inserted 180 degrees out in the socket, or the contact plate in the light may be reversed. Figure out what type you’ve got and get that one. IMO.. red turn on red brake/tail lenses.. suck.. These lights can be installed almost anywhere on any vehicle. On the plus side, I now carry a full set of replacement bulbs (the old, still good, incandescent bulbs) Turn signals are a rather simple electrical circuit involving just a few components: lights, relays, flashers, turn switch, indicator, and wire. Purchasing one and adding an assortment of extra lights also can prove to be difficult. If you use our 1-filament configuration, the rear left and right turn-signals will flash when you turn on the left or right turn signal. Test the turn after the wires are tapped. I've checked them. In this view, you can see the speaker opening on the left side of the image. Thanks to all. A few months ago I thought it would be cool to convert my turn signals and brake lights to LEDs. That’s why I ultimately decided not to carry on with the project. Once you have the new flasher installed, it’s a simple matter of changing the bulbs. VDUB2359 wrote: Thank you for your response. You can see it but you really have to look for it. I'm assuming you have 62-67 style tail lights? I had seen them on my friend Greg’s truck and I liked the crisp on/off quality. We recommend a couple different ways to address this problem, but first it is important to understand why there is a problem. The switch to LED’s addressed that, albeit a bit of a band-aid fix, and the other advantages of LED’s were just self-sold selling points. That’s almost 12x less power consumption. On the output side you will have the yellow wire for left turn signal only, green for right turn signal only, and red for brake lights only. Another reason behind fast flashing turn signals is that the screws are not installed tight enough to operate normally. Once you remove the set spring you’ll be able to remove the light. Somehow I thought LEDs would be brighter than incandescent bulbs but that’s not what I found. you can clean up the tail lamp grounds, the bulb contacts etc.. but may have a huge drop via the trun switch at the steering wheel or in the flasher can itself. flashing turn signal. NOTE: If you want to run LED lights or bulbs, you will have to run an electronic flasher unit. Now lets turn to the Turn Signal system used on early cars. To remove it, there’s one obvious screw, and a not-so-obvious set spring, that holds the light in place. Thank you for your response. It isn't that the brake light or turn light dims it is that the one seems to optically disappear. See the page in the shop manual below. When the signals flash double time, that indicates a bulb needs replaced. I got lucky installing them on my 2006 Rhino. Red bulbs show red through both amber and clear lenses. The brake light circuit and the turn signal circuit have crossed paths somewhere. Make sure that each light is equally bright (side-to-side). For some vehicles this is a common problem after updating the tail lights and/or other signal lights to LED/SMD bulbs. The problem with blinking brake lights is that since the US still allows red turn signals (both as separate bulbs and a single blinking brake light), it is not clear (without directing all your attention on that one vehicle) if the car is stopped, slowing, turning, or whatever. The hazard light button is essentially an additional power source and switch for the turn signal circuit. You can get them at places like Napa or here: Now, wire them in like this: Ok, now to wire in turn signals that share the rear bulbs with the brake and tail lights, you have to get a little creative... What you have to do is make the brake light wires and the turn signal wires combine in a way that the turn signal wires can override the brake … My grounds are good. how many volts is the bulb getting? This shows you how to hook up an AUX light so it can be used as both a turn signal and a running light. Active lights come in all shapes and sizes, and now, thanks to Jenna deBoisblanc , you can use an Arduino to make your own safety all-in-one bike project, which includes turning indicators, a strobe night light, speedometer, odometer, and brake lights. You will also want to make sure that the trailer lights are grounded. I recently installed the alternate tail light for my motorcycle that displays both turn signals, brake, and running lights. so check for voltage drops and clean up areas that give drops. The brake signal gets interrupted when you have the turn signal on, for instance, if you press the turn signal lever for a left turn, the brake light signal is interrupted for the left side and the power from the turn signal flasher is given priority and the left rear turn signal flashes, while the brake signal still goes thru the right side to indicate a brake condition on the right rear. Sorry for the topic hijack.. but.. Bruce started it.... :P. How to make brake light flash when turning. On the Montero, and probably on a lot of Japanese trucks, the flasher can be found on the interior side of the firewall between the engine and passenger compartments. When you hit the brakes with the turn signal on, it should blink on one side … Turn on the parking lights. I have not experienced what the OP has happening. Since LED turn signal bulbs draw much less power than the original factory būlbs, this will cause a sudden drop in the circuit's resistance causing the hyper-flash or rapid blinking of the turn signals. To improve my visuals on my tail lights when turning I am trying to have my brake light flash when I turn on my turn signal. The right side light does not work – no brake light or turn signal.
