Not sure if this qualifies. This is a project i have been working on for a while. Federal 184 beacons, grote par 46 View attachment 210350 imhousing, mars 888. But i put whelen led par46 and par36 lights into the vintage housing. It seems to be a great way to update old lights. I havent mounted everything into a usable configuration yet. I havent made any modifications to the beacons and everything can easily be converted back to origional sealed beams. Led par36 and 46 sealed beams are an easy way to update vintage sealed beam lightbars and helps with power draw.
If those lights were put on a rack and mounted on a vehicle, I like the idea of the speaker/light on the driver's side.
