The "hotrod head light" may just be those Guide's with markers / blinkers... ever the must be another way type, I spent $0.25 to $0.50 buying those encapsulated toys at the exit of the grocery store... gave the toy to the closest kid, tossed out the base keeping the semi clear "dome" for trial fitting into the marker bezels... there is one that is so close... pictured is too small but gives the idea... I cut for hight and a slot for the mounting screw and marker light housing's clearance with a hot [candle] knife... brittle... may kill any good deals on those headlights at a swap meet... HIH.
