New enclosed car trailer; back up light ideas

So I went and bought a new to me trailer- 1 year old and used once. The guy hauled a car from Michigan to Connecticut. realized the trailer was too big and traded it in for a smaller trailer the dealer said.
2019 8-1/2' x 24ft BT Scout fully loaded. 9998 lbs GVW- gives me about 4,500lbs payload.
Now I can take one of the cars, my quads or golf cart with me for a long trip or to the track.

What did you add to your trailer for back up lights. The fenders are not exposed so along the
back edge is all I got.
I will get a rear trailer picture as soon as I can. The exposed trailer rear is approx
4.5" around the back ramp ( sides and top to roof) is what I have to work with.
LED- possibly a few small off road work lights tied to a switch for "ON" and come on in Rev.
Let me see what you have done. Maybe off road bars
on slight angles outward.
S/N: we need a trailer section on this board.
Thanks,
Joe
