These are reproductions of the old Aris triangular chopper headlights. The overall dimensions of the light, not including the mount, is 5" x 5" with an overall depth of about 3". Very nice repop light with nice chrome and a swiveling bottom mount. 12 volt. These 'shallow' version of these triangular lights are way cooler than the deep, squared off versions
These lights feature a single filament 12V 55W mini-bulb..
