Anatomy and Restore of a 184 Power Light.


Site Guru
Thanks to Ex416, I found this FSS 184 Power Light Series A2, 6 volt. At first you might say "and ?". Until this time, I don't think anyone had ever heard of or seen a Series A2 184. We did not know it existed. Before this we though the 184 started off with Series A3. They were asking way to much for it, although, for a collectors point of view, it is important. The price dropped twice and then I made an offer and they accepted so I now have the light.

I was very curious as to how it would compare to the A3 and later lights so when it arrived I jumped right in and disassembled it. Other than being 6 volts I only see three notable differences from the A3. The Axel is smooth where the light holders mount, where in the A3 it is crosshatched. The tag is not embossed but stamped, which I haven't seen any Federal tags just stamped. It has four mounting bolts around the base which I suspect is for mounting to a plate and post.

Maybe someone else might notice a difference. I will post the process below for disassembly and show the components.

This is how the light arrived. It did have a fairly new Dietz dome and the retaining band.

Removed the bulb holders. The base is chromed brass and the top has a lot of chrome missing,likely from a dragging bulb holder.
