Today I installed the cabin flood lights that i can steer to the panel or the floor. I have two of them: one is switchable between red and white, and the other is blue. Both are led dimmable. I mounted the stem base with M3 rivnuts and screws so that I can replace or repair if needed. I also installed clips to hold down the wires and cable. Once the upper and lower skin is installed on this arch, there will be no practical way to get inside so I'll be testing everything before closing it up with rivets.
