Harbor Freight here had no lights
but I ran over to the local Menards and picked some up, along with a new wiring harness, even though that wasn't necessary. Rewired the whole thing and got the new lights working. A few minor tasks left to do but it should be ready to go for the next trip. I didn't mind depending on just the magnet lights, but it will feel better to have two sets of lights back there, just in case one gets squirrely and I don't notice right away.
