The Stovebolt Site Forums The Shop Area The Electrical Bay Dome light / Headlight switch connection question (1957 3100)

The bulb should be single filament.
The only wires going up the a pillar should be the two for the dome light.
Unless someone has changed the socket the two wires are just completing a circuit thru the bulb. Easy to test with a multi meter. test without the bulb then put the bulb in.
The socket should not have any contact to ground via the holder light metal.
if the socket has two posts on the inside the that is the circuit and the bulb should only be using those two posts.

orange and white or gray and white have seen both.
Does not matter as long as the two wires going up and back are the same circuit.
Yes some other post/wires are there for things like door or floor lights i am sure that came later.


DO NOT ATTACH Ground additional ground wires to the switch. The "Ground" markings are telling you that post is already connected to ground via the switch metal to body contact.
