Hi guys, just came in from the shop after roughing in the port wing approach light. I simulated the curved leading edge on both sides of the lamp and I simulated the top and bottom sheeting to get the right depth of the lamps placement. Thanks Charlie for your help. Due to the lamp reflector, the light fixture is about 7/8ths of an inch in width. It needs filler to be applied and the aluminum tape to cover the bare areas. O'yea, it works also. Will micro switch it to the flap servo, when they come down, the lamp will come on. They lamps system is a flashlight reflector, a PR20 bulb and a 9 volt battery. Chic
