Reverse lights not working
I have a 81 f100 ranger and my reverse lights don't work anymore, I've checked the bulbs and they are still good and the switch looks to be good, what else could cause the lights not to work?

As Ford states, "use a pin to pierce the insulation to check voltage"
I usually will go to the end of the circuit and test the plug.
If the front end of the circuit has power and the end of it does not, visually look down the wire (you have to twist it to see the other side for chafing).
If no luck on finding a break, start using the pin method.

Of course, the grounds in the sockets for reverse, and stop/turn/tail & front marker/turn are known to be rather poor. The little metal tab that is supposed to contact the side of the bulb base can get bent and/or corroded after this many years.......

Well, if you have a meter, do like was said and follow the electricity... test for power on the incoming side of the switch, then the outgoing side of the switch once the switch is activated... then at the other end of the wire that connects to the outgoing side of the switch... then to the socket, then to ground.
