So the guys who I bought these wings from had planned way back in 2007 to do roll your own landing lights. They had cut elliptical holes in the leading edges for a couple of small halogen lights that I'm not going to use. I'd like to utilize those holes for LEDs if I can find a reasonable solution that will fit, but I'm not sure the hole extends far enough under the bottom trailing edge to throw light where it needs to be on approach. I'm planning to build this at a tail dragger and the challenge gets even bigger when you start thinking about aiming taxi lights in that configuration. Somebody from VAF previously sent me a PFD of the template to cut the Duckworks hole in the wing. Unfortunately, the holes that are already cut are wider than the template. I contacted Duckworks a while back & got the dimensions of their lens blanks and when I explained what I had they told me that the standard blanks only needed about 3/8" min overlap on each side and that they were oversized enough before trimming that I would probably be okay with the standard ones but that they could cut oversized ones for me on request. I think that the only way to be sure what I need to do with this hole is to settle on a LED set, install them, and then see what I need to do with the hole, so I'm going to order lights from Flyled tomorrow.
