ABSTRACT:
A motor vehicle daytime running light circuit is disclosed in which the high beam headlights are energized at a reduced intensity in response to a predetermined vehicle operating condition including, for example, the headlight switch being in the off position. Power to the high beam headlights is supplied through a field-effect transistor that is modulated by an oscillator operating at a frequency sufficient to maintain the headlights at a constant intensity. Circuitry that senses the predetermined vehicle operating condition enables the oscillator and disables a high beam indicator.
