I put a pair of China's Best brand LED floodlights on the back of my trailer. They work great coming in to a dark site at night.
Should be easy enough to do on a TC... If you can find the wiring harness for your Bargman 7-way, you can tap into the reverse line there, or the harness for a tail light and pickup reverse there.
If you're looking at more than 20 watts of lights, consider using a relay to avoid taxing the existing lighting circuit.
