I have an adjustable eyeball type LED (red) light to use for a cockpit light. My current plan is to mount it between the bulkhead halves behind the seats (photo #2). The bulkhead is at such an angle that even the adjustable head of the light would not be able to point downward enough. So I used a paper template to create an angled bracket to fit between the bulkhead, and to face downward.
Photo #1 shows the light next to the bracket.
Photo #2 shows where it will go. I have enough room to get some rivets in there.
Photo #3 shows the wings in their new home (thanks to my wife for the assist!). As suggested by others, I ties the trailing edges together at the root ends, to keep the wings from accidentally rotating out of their cradles.
