Just a note of warning:
A lot of heat can build up in this area when the lights are on in there.
I used Kill-A-Watt LED position lights, and NOVA strobe tubes.
The strobe tubes get hot. I have heat dimples above the strobe tubes from ground testing. Perhaps the air flow during flight will keep mine cool enough, but prolonged ground running will be a problem.

Consider this when you mount your lights in there.
