I checked the fuse to the brake lights and it is fine. Im thinking it may be the brake light switch on the brake pedal but i have no idea if the strip at the top is connected to that too.
Both of my brake lights went out at the same time, the strip at the top works. on 1992 Cadillac Seville
Check the bulbs first, but it sounds like the turn signal switch has gone bad.
POSSIBLE BAD BULBS, THEY ARE ALOT CHEAPER NOW DAYS AND DON'T LAST LONG
