The fact that the light bar lights up means that it works. If the fault is consistent, I'd be more tempted to look for the fault at the brake pedal - where the switch for the light is. As your existing brake lights work correctly, next step is to see whether they use the same switch, as per @Brian's comment. It may be that the LED bar has been wired in ...

After much deliberation on going to repair shop, I figured I would at least poke around as it could not make anything worse. Here was the problem. The negative terminal wire soldering point was loose. I fixed it this way: Unplug the LED array. (Pictures to come) Video of removal process here on youtube Remove the rear plastic shroud(with a few upward ...

Each bulb have some sort of life time expectancy so if two lamps are installed at the same time and one fails after a long period of time you can deduce that the other can be close to failure as well so for security some people and manufacturers ($$$$) recommend replacing both at the same time. The thing is that there is no rule since a lot of factors come ...

Its fairly common for these to burn out sockets for the bulbs, and even often on both sides at the same time. The socket can be removed asa separate piece, and it is fairly likely melted and/or burned

Sort of. Older filaments in headlights can be noticeably duller. If you are OCD, it might benefit you. Typically when one bulb goes out, the others that were replaced at the same time are probably near their end of life. Or, perhaps not. I don't replace things that aren't broken. Otherwise, it's just more money for the parts store.

A good service manual will have extensive wiring diagrams and possibly troubleshooting procedures and connector locations. With that and a multimeter, you can easily track the problem down. I prefer factory service manuals over Haynes / Chilton / etc, but they're not cheap. Looks like the one you would need would be $150 from Helm. If you can verify the ...

The most common way to handle this will be rubbing compound and preferably a power drill or buffer. If this is a tail light it is likely a plastic of some kind. You can polish out minor surface scratches with rubbing compound and a buffing wheel. This of course depends on if this is a scuff or what most would call a scratch. If the depth is significant ...

If the tail lights were hot during the swap you may have broken the filiments. Bumping a bulb that is on or been on recently can cause the filiments to fail. Remove the bulbs hold them up to a light and see if the filimant is intact.

Its a mixture is tradition and function. Red has been used to signify "Stop" much longer and in many more applications than just motor vehicles. Stop and Do-Not-Enter signs are used everywhere. Possibly, although I can not confirm or cite a source, in history blood was used to mark doors and entryways that should not be entered and therefor the red color ...

I've had a similar problem before and it turned out to be the socket for the bulb was bad. I'd start with inspecting wiring that you can see, but proving wiring "good" is pretty much impossible (and replacing it is likely to be a major chore). It might just be cheaper/easier to try and replace the socket first and see what happens. Sorry I can't be more ...

Break out the multimeter. Start at the bulbs. Verify the ground is good and then and work your way back towards the fuse box looking for an open as long as the wiring is accessible (Have a friend / brick depress the pedal). Assuming you haven't found the trouble spot, move to the fuse box and go the other way. If you're lucky the problem will be where you ...

My mom's Prius HID bulb died (under warranty) so she took it in to get it replaced. The dealer replaced one of the bulbs and it was a completely different color than the original. I finally bought her two new bulbs from Amazon and replaced them for her because it was so bothersome. In a situation like that it is definitely worth it to replace both at the ...

I finally got this figured out. The housing inside the actual tail-light assembly had become deformed, I guess due to heat, thus keeping the light-bulb housing from making proper contact with the tail-light assembly. A new tail-light assembly fixed the issue. Thanks, everyone, for your help with this issue. UPDATE: Recently, the same thing happened on ...

The parking lamp/headlight switch applies power or ground so the circuit would be open if you were testing with the switch off. Same with the turn signals. The tail lights are on separate circuits. They don't share a ground. Does the car have an aftermarket trailer harness? If not your going to have to remove panels and visually inspect the harness for ...

I had the same problem.. but when i shoved the gear shifter into reverse hard and shook it hard it flashed. So what i had to do was take my dremmel and grind the part of the switch base below the threads down to allow the threads to screw further into the transmition. I took off about an 1/8 of an inch and Now everything works as advertised.. :-)

Thanks to some helpful people here and on the Australian 4wd forums and a local gearbox repair place I have found a solution. Apparently the gearbox the the MJ Triton uses a ball bearing above the reverse switch. The gearbox pushes it down (pushing the switch) when in forwards gears which opens the circuit and turns the lights off. In reverse it lifts up ...

I did some research on some Saab forums. I found that typically on US bound Saab 9-5 a bulb is installed on both sides. However, the metal circuit on the passenger side is cut to disable that side. This is to prevent the rear fog lights from appearing as brake lights (there are arguments about the legality of dual rear fog lights in certain US locations). ...

I would still check all your lighting fuses, sometimes your brake lights/taillights will be on separate fuses.

Last time I saw that problem it ended up being the socket on the vehicle. Could also potentially be wiring of course.

They are the same tail light except the SE-R tail lights have black surrounding the lights behind the lens instead of chrome like the regular models.

I had the same problem, turned out to be the green / white wire on the right rear cluster. Simple easy fix.

You're exactly correct in that thinking (I replaced the bulbs in my old Volvo once and it caused it to think they were out because the bulb was slightly different (these weren't even LED's; just a different filament or connector or something, I forget; no tolerance at all on that circuit). I don't know if there's a standard way to fix this (other than use ...

If you look in the trunk near the taillight you will find some plastic screws that hold the carpet in place. Using a flat head screwdriver remove them by unscrewing them or prying them out. Moving the carpet should reveal the mounting bolts for the taillight. It will most likely require a 10mm deep socket to remove the nuts. Disconnect the lamp sockets from ...

As a general rule, your new bulb should be in good working order. Just to make sure swop it with the matching bulb on the other side of the vehicle which you know is definitely working. If this bulb now operates in the first lamp assembly you now know the problem. Turn your ignition on off when you check the bulb for working as some vehicles use this as a ...

The first place to look for the headlights would be the fuse panel(s). Often there are two: one inside the passenger compartment, either at the driver or passenger kick panel or on the side of the dash where the door covers the dash on the driver side. The other is the engine compartment (in a black plastic box--diagram will be on the inside cover or on the ...

I'm assuming that you are testing the brake bulb voltage with the brakes actuated. There is high resistance somewhere in the circuit causing a voltage drop. For example lets suppose there is 10k ohm of resistance in the brake light switch. When the bulb is out and the switch is activated there is no current flow. A good meter has 20M ohm of resistance and ...

I'm going to answer this in a general way because for someone to tell you what the wires mean, they would need to follow this procedure, or have access to detailed wiring diagrams for your car. You'll need a multimeter for this, and you'll have to take apart the brake light as if you were changing the bulbs so you have access to the bulb sockets. I'm ...

If you are looking to figure out which wire goes to which, an easy way to figure this out is to have a source which produces 12vdc and has the two leads for (+) and (-) with probes attached, plus a pad and pencil to mark down what is what. After you have your 12v source and other supplies to get started, take the bulb section out of the housing so it looks ...

Blue Green is the indicator wire for the left rear, blue brown for the right rear. Assuming USDM.

There are LED bulbs with ballast, or you can purchase ballast separately to keep flasher units happy. http://www.superbrightleds.com/carbulb_notes.php#turnsignal
