How to fit "G J C" approved headlamp mask
Remove glass from car headlamp & mark mask to the size and shape of glass centering the glass slit and celluloid insert. Cut mask with tin snips to fit the headlamp instead of glass with this side inward towards the globe. Adjust the headlamp downward 2 degrees from the perpendicular so that the light beam strikes the road 10 feet from the front of the car.
* Important - Do not alter the angle of slits over slits.
