I decided to install the landing lights in the leading edge prior to attaching the leading edge to the spar. I went with the Duckworks round 100w halogen kit for each wing and ordered through Van's--should be dellivered this week. In the meantime, I finished dimpling the upper wing skins, then began prepping the lower wing skins by removing the vinyl along the rivet lines. Once deburred and dimpled, I'll set them aside and wait until the light kits arrive.
