It hit me one day that since the LED lighting operates with 12 VDC, adding a simple micro-switch to the door would eliminate the need for a wall switch. So I picked up the micro-switches from Radio Shack for $3.49/each and tapped an always nearby 12 VDC source, and now I have lights that turn on/off as the door opens/closes. If you look closely, you can see the switches mounted at the top side, with all wiring tucked neatly away never to be seen.
