Abstract
The present invention utilizes a dimmer switch for alternating the lighting direction of a vehicle headlamp, but does so utilizing control apparatus that ensures that only low beam-directed light is emitted by the headlamp when the headlamp is turned ON. The possiblity which might be presented if oncoming traffic is suddenly met with high beam-directed light when an automobile driver turns his headlamps ON is thereby averted.
