Adaptor for Light Unit, no wires, English End
For converting to semi-sealed beam lamps, this is the original style, British home market socket, but it is adapted to fit the American style 3 contact 'plug' style. This allows you to change out the US style sealed beam headlight back to the original semi-sealed European style headlamps. You would need a pair of 37-006, 37-006A or 37-006-010.
Uses bulb part number 35-101
