Are all of the other tail lamps working, specifically the parking lamps? I ask because they get power from the same place.
If the other lamps are working, we need to check the connector for power at the license plate lamp.
At the light connector, probe the red wire to check for power. Do this with the lights on. (See pic below)
If there is power, confirm continuity to ground on the black wire. (See pic below)
