It has a kind-of 60's art deco look. I don't see these in most of the photos of the 31's.
Was this light standard or an add-on? Any information would be appreciated.
31's came with the Running Lights incorporated into the Bow Chock.
Over time the Stock Chrome Plated Bronze Casting gave up its Shiny Chrome finish, many had issues with lenses deteriorating, leaking and such that they gave up on them and went with over the counter Running lights.
Others, such as myself removed then had Chock Re-chromed and sealed up unit with new bulbs.
Then some went with Dugs Solid, polished 316SS Bow Chock, (less running lights) for a unit that will outlast our kids kids with a yearly wash and wax.
