Reverse lights on a 1967 Mustang

I have replaced both reverse lights and cleaned up the sockets. Neither one works. I recall reading that there is some type of relay that may be bad if both are out but I cannot find that thread now. Can anyone tell me where to look next?

Thanks!

When troubleshooting, use a meter to verify you have 12v at socket. There is NO relay. A big mistake sometimes made, it uses a special 1142 bulb. Not a common 1156 or 1157 bulb. Make sure shifter backup switch plugged in a works. But the wrong bulb in, it'll blow the fuse.
