Brake light problem
My 54 truck has only 1600 miles on it. The other day I noticed the brake lights work then don't work. The brake light switch is one of those waterproof kind. I got under the truck and when the brake lights did not work I touched the part that is against the brake arm and it worked. Then I come back later and try the brakes and no brake lights. I pump the brakes and they work. Then later they stop working. The taillights are fine no problems. All the wiring is new from Painless and everything else electrical works fine. Any ideas? Thanks.

Re: Brake light problem
Possibly the switch is failing?

Re: Brake light problem
I'm not quite following what you are writing but it sounds like either your switch is going bad or you have a suspect contact between the wire end and the switch.
I'd take a look at the crimp on the wire end to make sure that it was tight on the wire and then make sure that the wire end was making good contact with the switch. If the switch has slide terminals rather than screw terminal you might want to squeeze the female slide terminal slightly so that it fits tighter on the switch.

Re: Brake light problem
Could also be the distance the plunger compresses or releases when the pedal arm moves, had the same issue with my 4wd selector switch. Moved it 1/16" and life is good.
