Depending on what lights you're looking at:
The 2 small upper lights towards the very top of the front cap that are about an inch round are orange running lights that are on while plugged into the tow vehicle.
The two larger lights close to the center of the front cap are LED flood lights for hitching and general visual. The switch for those is on the front wall of the pass through storage on the driver side.
