Some additional details as to why you want this particular (unusual, rare, vintage, obsolete) item, if you care to share those, might help others here to help you more effectively.No one with any idea?
Thanks, but those lights aren't at all a match for the Rub-R-Lite (what I can google any way..)Early dive light.
Trouble was they were finicky and were not easy to figure out something as easy as changing a battery.
You might check into Tekna brand dive lights if you seek something modern and inexpensive. And they are US made too.
They trade as Tektite these days and the owner is a CPF member.
