When I hit my brakes, only the top brake light works. All my running, parking lights, reverse and turn signal lights work and light up when I turn them on. All 4 red bulbs work in the back, but wont light up brighter when I hit brakes.
Only fuse I saw was for LH and RH tail lamps... there’s one for brake lights, but I figure if that was blown the top one wouldn’t work either.
Is there a double filament in the brake lights and maybe just the running light filament is working?
Not sure what to do, before I go taking my lights off.
