SOURCE: LED Brake Lights diming

I had the same problem with my 2004 TL, and it was the brake light switch. It is very easy to replace. (10 min) I ordered one from Rockauto.com for only $6.95. To replace: Remove the black cover under the steering wheel, down by the fuses (held in place by rubber pins and clips - no screws) Locate the switch on the arm of the brake pedal. Unplug the switch, twist the old switch out and install the new one - it's simple!

the problem is probably your turn signal switch. I know it sounds weird, but the brake lights work through the switch. If the third brake light works, then the brake light switch works, the turn signal switch works the lower brake lights. It's the switch under the steering wheel inside the column...not the easiest or cheapest thing to replace, but should fix your problem. If you decide to do it yourself, tie some wire to the connecter on the end of the switch wires at the bottom of the column...that way when you pull the wires up throught the column, you can use the wire you tied to them to pull the new connector and wires back down through the column.

SOURCE: bottom brake lights and hazard lights do not come on. All other lights work including top brake lights. Fuses and bulbs checked.

Check for power out of brake light switch by brake pedal. Of its faulty , the 3rd brake light will still work. Hope this helps

The third break lights are LED and the circuit board may have gone bad or the solder may have gone bad. The circuit board is built in the third brake light and is a seal unit. You may have to replace the unit, there is a relay for the third brake light and that is located on the glove box behind the panel that say's relays. There are three relays in there, the center is for the fuel pump and the two out side are for the A/C and third brake light. Just swap them around and see if the brake lights come on. Good luck and keep me posted.

LED does'nt work on tail light but conventional bulb is working


Your description indicates the replacement led bulb is either defective or not a direct replacement for the ordinary bulb, which I assume is a 2-filament stop/tail type because if you have a good ground and both supplies are present as indicated by the fact the ordinary bulb worked fine, the led should similarly work if it is good.

I suggest you check the supply voltages while the led is fitted. It might happen that some device in the lighting circuit is monitoring the amount of current or resistance of each bulb and will not provide a supply unless it "sees" the correct amount.

Sounds like your brake light switch, located on the brake pedal, has gone out. Shouldn't cost to much at auto parts store. Thanks for using fixya.

Right brake light out 2004 Prius


Th other post is incorrect, the 2004 has LED brake lights that are part of the tail light assembly. you have to replace the whole assy. There are two screws that hold the assy in, they are both covered by white cable clips. The clips just pull off and then you can use a 10mm wrench to remove the nuts on the screws. My brake light stopped working and during the removal, the LEDs started working again, hopefully you will find the same situation as the LEDs are supposed to last for years.

Led brake light works at half brightness


Check the current to see if it is AC instead of DC. An AC current will power the LED light but only on every other cycle giving you half brightness.

The brake lights my 2000 Chevy Blaser do not work, the turn lights work and the running lights work and the brake light on top of the blazer is working


We bought a 2000 Blazer in '02 and one day I noticed there were no brake lights, but the 3rd light on top worked fine. I did some research online and found out there was a recall on this problem due to the hazard switch on the column. I also found out if I wiggled the hazard switch a certain way, the brake lights worked. I was able to get by for awhile by wedging a 'widget' beside the hazard switch button and the hole in the column cover. This worked fine until someone would knock the widget out of place.
I finally got around to having the switch replaced at a local dealer. All was fine until last week when I was told the brake lights were out again and I found out my hazard lights didn't work either. I changed out the switch assembly myself this time, and once I had it out I saw what happened. The brake light voltage comes in to the assembly on a white wire, and the first contact this goes through is on the hazard switch. In my case the contact had obviously overheated from the brake light current and melted the plastic holding the contact in place, thus breaking the circuit to the brakes. Either a poor design or too much current for the circuit to handle.
Soooooo now I am in the process of replacing the four bulbs in the tail/brake light assembly with 3 watt Luxeon LED plug-in replacements. The current draw of the original bulbs was measured at 2.2 amps at 13.8 volts, times 4 bulbs makes about 8.8 amps that goes through the contact in the hazard switch whenever the brakes are stomped. The LED replacements draw .2 amp each, so times 4 will be .8 amp or less than 1/10th of the original equipment bulbs. These LED bulbs in my opinion are as bright or brighter than the original equipment and hopefully will help from burning out another switch assembly.. David
