Back up lights
I don't see any reason why you can't do this. That piece is fairly thick but hollow and the wiring for your right tail light should be in there anyway.
The lights you are talking about would have to be fairly small - less than 2" high.
I'll look on e-bay for you and see what I can find. Also, they make lights that go into the ends of you bed sides upper roled edge - they cap the tube ($110 !!!!!). Might be an option as well - either on the bed or in the back end.
