Nice design! I like the use of the retaining pins to secure the lights. I'd like to try something similar.It didn't take long before I designed a LED pair of adhesive backed strip lights intended for daytime driving lights, attached to the very rear of the headliner behind your head, using the OEM poke in retainers. I wired them to a separate switch from the second battery, fused them to a second fuse box I created for such. It's got a bitchin' dome light now. Almost too bright to kick on at night driving down the road if you're not ready for it, which is why I placed them deliberately behind the driver's head, not above, certainly not in front where the OEM set is. I'll try to find a pic and post it if you think it might help you.
