I have a '67 RS that I have almost completed the restroration on. One problem though, I cannot seem to determine why one of my brake lights will not work. I've installed a new wiring harness, checked the bulbs and numerous other things to no avail. Can anyone help or give me some other suggestions? I would greatly appreciate it.

In most cases it's a bad ground, or the socket contacts are dirty.

My brothers headlights go out frequently on his 88' camaro ,
it's always the sockets.
