Hi Cliff.
Do you happen to have a picture or know what size
12v socket I need for my license plate light??
Mine was rusted to dust.
I bought one, but by the time you get the bulb in it there is no room to put the metal cover piece over it.
I have made every thing new for it, a backing plate and a urethane piece to replace the stone hard rubber piece that was there.
I'm doing some small stuff for the trailer as I wait for the snow to go.
Hey its only 2.5 months til April now!
Hope your research is proving fruitful.
S.
