This is a Flarestat 105 head light switch from the 1950's-60's, for use on any vehicle with a snow plow (universal). The piece is used, cleaned, I have not tested, no original packaging or instructions, sooooo buyer will have to DIY figure out the wiring (reason I haven't tested). The switch does have a red plastic pull knob that lights up when head lights are in use, glow knob (see last photo above).
