Tail lights

[FarrellyT]

New calipers are on order for my 79 corvette, so until they get there I’ve been working on the electrical system. When I went to put in new lights for the rear end of the car the directional flashers stopped working (even with a new relay) and the reverse lights don’t turn on. I’m thinking it’s a harness problem because the bulbs are brand new, any input would be great!

did the signal lights work before you put new bulbs in ? should be a fuse for them. key must be on for reverse lights .

Yes worked before but very dim

Hi FT

It’s almost always a ground issue...
But sometimes not...
But most likely is..
Check you ground connections and wiring condition.

I agree with nascar03, sounds like a poor ground.

Cleaned the ground and they still didn’t work I’m going to probably pull out the whole harness and take a look at the wires, when I ratted the harness they turn on and off so must be that

If you are sure it isn't a ground issue, it likely is in the harness after all its almost 40 years old and they get brittle and worn.
