How to replace third brake light on 2007 honda civic ex?

The third brake light (high mount break light) for the ex series 06-07 civics is actually an LED assembly not a regular bulb. 9 times out of 10 the assembly will not need replaced and you may see on occasion that the light will still work but not consistently. So there is no need to pay the outrageously over priced fee Honda gives you for the break light. The problem is actually a short in the wiring on the PCB board of the assembly. In order to resolve this first tell Honda what a dumb design it is to integrate an LED break light assembly in 8in subwoofer housing. After you do that, locate the wiring harness in the trunk for the third break light and detach it. You will then need to put all the back seats down and remove the rear deck, I found it best to remove the bottom joints first and work my way up then left to right. You will see indents where you will need to push in and up in order to start getting the rear deck to give be careful with this portion as I actually cracked mine slightly since it's just plastic and it's a little tight which requires gentle man handling. If it does crack there it's really not a big deal since once the seats are up as normal you can't see this area. Once you have the deck removed unscrew the black subwoofer

bracket on the bottom of the deck. Then remove the screws that hold the LED assembly in place. You will see the solder joints on the belly of the PCB board. For the most part all that needs to be done is a reflowing

of the old solder. I just added a little extra new solder to get the old solder hot enough to liquefy and then settle. Once the joints are re-soldered

I would suggest adding some electronic silicone to the joints or foam under the PCB board and plastic assembly to provide cushion from the damaging vibrations that this assembly clearly cannot handle. (Maybe even to both) Be sure to plug the assembly directly into the wire harness to make sure it's working properly and jiggle it around. If all is well reassemble, save yourself $180, and go pass inspection. Peace. (YouTube
