Abstract
The fact that the use of the two-filament bulb with a parabolic reflector to “depress” a headlight beam is always accompanied by an elevation in certain parts of the beam does not seem to be generally recognized. The extent of this simultaneous depression and elevation is computed from the fundamental theory of the parabolic reflector. Certain implications and conclusions bearing on headlamp design are pointed out.
