Is this not a 12 volt regulator?It was installed in my newly aquired A 10 which had a 6 volt battery.

A quick google and the aftermarket has 6v rb108’s for sale, and that there were 6 and 12v versions of the rb108 made by lucas.
If the bulbs are 6v and its charging ok, you probably don’t have mismatched parts?

The voltage should be stamped on the back. The part number and date should be there also.
