I’ve got some guide headlights with a plug Im not familiar with. Anyone know if the female side is available anywhere?
You might be able to adapt some of the Model A headlight hardware as Squirrel points out. The Bratton's Antique Auto Parts catalog has a nice diagram of the stock A headlight that might be helpful. The Model A headlight is male and the conduit ferrule has an indentation that secures the pictured insulator. Kind of opposite of what you need. The headlight wire plugs as pictured will insulate the plugs but you need a way of securing it to the light body. The part you need look's like it pushes in and turns to lock it in place. Bratton's might have a diagram on there website, www.brattons.com.
