Sola Red filter cap (RODAM)

This is a cap fitting for the Sola from Light & Motion. Since all the dive light models Sola share the same casing, this will fit almost any Sola light. It was design for my Sola 600.
I used a 2" (50.8mm) plexiglass disque, transparent red. Thickness is 2.75mm. There are many on ebay. Here's the one I got.
