Grimes Co. makes eyebrow lights for the aircraft industry in all sizes. plus light assemblies for backlit panels. Which are a whole new can of worms to get into. Due to the inherent frugality of hams most will have cardiac arrest with the sticker shock. I have made full aircraft panels using Grimes systems. I think in the 60's when we did this panel for a Lodestar it was over $15,000. Hank KN6DI
