Hi everyone, my 3rd brake light that is located inside the cabin by the sub is dead. I'm just trying to figure out what type of bulb I should use to replace it. I checked in the lighting forum and I think it is a Sylvania 921 and is called the high mount stop light? I just wanted to verify with someone who has changed that bulb out.

i had to replace those bulbs too. the manual i think said 921 like u stated...but when i tried to put it in, the bulb was to phat to fit in the little protective covering. i just replaced them all with 194 bulbs. works fine. fits perfect.

hope it helps.
