Headlights, taillights or turn signals do not work?

With all of those out I would start looking in the fuse and relay box. There are different power feeds for the lights, but most are fed in that box through a couple relays. I would use a test light to start testing the fuses and relays in that box.

The only other common item is the light switch.
