short to ground somewhere. Try jigging your light connections or wires around your tail lights or where the harness goes thru the frame before getting to the hood connector. Just shake wires. Leave your headlights ON if you jigging the short the breaker will turn the lights on and off. You are talking about a lot of area of wires to find a specific short. Just best to start by jiggling wires at connection points to see if it is just something simple there before replacing parts.
