Wondering if anyone can help. I have a 69 TBird. Reverse Lights aren't working. It calls for 1156 which are new but socket has the double prong in it for an 1157. Guide slots are also for an 1156.
The single prong won't make contact. Can anyone with a 69 look at their socket and see?
I've since exposed the wires and have no power to lights in reverse. The neutral safety switch seems to be working.
Gotta love electrical gremlins.
