I began the process of installing the new and improved LEDs in their housings. The bases have new holes drilled in them, but they need to be held in a very close-tolerance position inside the housings. Using a test assembly as a template, I glued each LED into its base. Once these dry, the LEDs will be inserted into the white collars, sticking out about 0.5 to 1.0 mm. (photo 2 below). Then they will be inserted into the black lens housings. The bases will be glued into the housings to complete the basic assemblies. After than, I'll start on the labels. Photo 1: The LEDs: 6 blue, 2 red, and 1 yellow, along with the glue I'm using.
