Hey, I have a problem with my right rear brake light. When I hit the brakes it doesn't light up.The bulb is ok, when I have the running lights on it is lit up, but it doesn't get brighter when I hit the brakes. The reverselights and turn signals work fine. Any ideas on what the problem might be, how to check it and/or how to fix it? Thanks!

 

There may be 2 filaments in that bulb. Both must be good.

 

Ah I see haha! Yeah one of the filaments is busted. I dunno how I missed that. I can get a new one down the street for a few bucks. Thanks man!
