How To Repair 2005 Prius Led Brakelight

I had the passenger brake light become out on my 2004 Prius a few weeks dorsum. The brake light is comprised of a bunch of individual LED lights. I did some searching online and constitute out the 'prepare' was just to supercede the whole tail calorie-free associates. Looking up prices, I plant them for well-nigh $75 shipped. Non horrible, merely I figured I'd accept a crack at fixing it earlier plunking down the cash. I'll document the findings hither.

First off, this is the (driver's side) tail lite associates. The black portion is the brake light, and each section you meet has a normal 1/8" or and then LED in it. This is the portion of the light that stopped working on mine.

And so, I ripped mine out of the car. Its a fairly quick and painless procedure. This is the back side of the calorie-free once removed.

The foam piece is merely held on with some agglutinative backing, so I peeled it off. The yellow and blackness wire you see along the summit of the assembly goes to the LED excursion board on the left side of the picture show. From the LED circuit board, they get all the mode to the correct side of the picture to some other circuit board that consists of a agglomeration of resistors and a diode.

The other circuit lath is tucked away behind this white plastic piece.

Here we accept the other circuit board. The resistors are all rated for 2W of power. The ones on the right are xx ohm, the ones on the left are ix.1 ohm. At kickoff I thought this was a voltage divider, but I'yard now guessing its merely limiting amperage to the LEDs. When I tested everything on this lath information technology all appeared it exist performance properly. I didn't see whatever cracked solder joints either.

The next step is to get at the LED circuit board and run across what the effect is. All the same, this is a bit more than difficult as its within the sealed tail light assembly. There is no access to it unless the rear lens cover is removed. I attempted to do this with the same procedure that headlights are disassembled, baking for a few minutes in the oven. This did non work at all. The glue didn't soften like the urethane headlight gum. I cracked the clear plastic in a few places before giving upward. Also the time in the oven melted some of the blackness backing plastic. I had to take a heat gun and melt it back into place to reinstall the light for the time being. I now have a new tail light on order, but volition continue this analysis once I go the new light installed.
