Jim, the "Grimes" retractable landing light is a combo of off the shelf parts and some scratch building. The actual lamp portion comes from Heli-Factory in Germany. More info here:

The assembly, which is very nice, is designed to be installed to the bottom of a fuse and have the lamp be flush with the pivot mechanism above. A micro servo is mounted directly to the lamp "arm" for the retract function. In my case, in order to fit it within the pod, I needed to remove the servo, cut the mount in several places and reduce the overall footprint to make it fit. I used JB Weld to keep the aluminum mount together after all of the cutting and material removal. The pod is two pieces of vacuum formed plastic. I made a plug in the correct shapes out of balsa and styrene. After getting them just right I sent the pieces to Joe Howard and he was kind enough to make some vaccum formed parts. (Hence, the steak sandwich Thanks again Joe.) I trimmed, cut and assembled the shells and then mounted the lamp assembly inside. It was a lot of trial and error. I added a lever to the lamp mechanics so that it could be operated via a servo mounted above the pod and then put a small micro switch inline so that the lamp would come on when fully deployed as per the fullsize. They are not up yet but I'll have some build pictures of this process on my Vario gallery page. You can get there by clicking the HOMEPAGE link below.
