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 (photo 2 below) and then 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.
The LEDs: 6 blue, 2 red, and 1 yellow, along with the glue I'm using.
The LEDs will stick out of the white collars about 0.5 to 1.0 mm.
