Nissan Repair: 92 nissan pathfinder, nissan pathfinder, headlight switch

Question
My plate lights are out. I checked the bulb and fuses. The wiring seems to be fine. What could it be?

Answer
John,

The power feed is from the headlight switch and works with the parking lights.  If the circuit gets no power when the parking lights are on I would assume the the headlight switch had a problem unless someone has installed a trailer wiring kit.  Otherwise it is the headlight switch.
