Abstract
A vehicular lighting system includes low beam headlamps, high beam headlamps and a control unit configured so that during operation of the lighting system, the control unit determines the operational status of the high beam headlamp and selectively adjusts the illuminating intensity of the low beam headlamp. In particular, the brightness of the low beam headlamp can be increased during periods where the high beam is not being, thereby allowing the low beam to more closely approximate the brightness of the high beam, but without the glare associated with conventional high beam patterns. In this way, artificially low illuminating intensity limitations placed on the low beam headlamps can be overcome during periods where the lighting system is operating but the high beams are not in use. In one preferred configuration, at least the low beam headlamps are made from numerous individual light-emitting diodes that can be separately controlled in order to achieve the adjustments in low beam headlamp illuminating intensity.
