Contained inthis casing is an arc lamp of special design, equipped with anenclosing globe of heat-resisting glass and mounted with thearc at the focus of a nickel-plated copper reflector. Thewhole construction is simple, convenient and durable. As the design of cars varies greatly, no attempt has been.

The headlight is provided with hooks andadjusting screws, so placed that little difficulty will be foundin arranging a suitable hanger, and it has been left to thepurchaser to attend to this detail as suits him best. Special care has been used in the design of the door of theheadlight, the frame of which is an iron casting swung on asubstantial hinge. The door is locked shut by a wing nutwhich prevents any possibility of its swinging open while onthe road. The glass front is made in sections, for the purposeof avoiding breakage by taking up the jar and by eliminatingthe strains, due to expansion and contraction, to which a one-piece glass front would be liable.
