ABSTRACT:
An incandescent lamp for use in the headlamp of an automotive vehicle includes a low beam and a high beam filament mounted in a gas-filled, sealed envelope. The filaments are generally parallel, in closely adjacent, overlapping physical relation and each filament includes first and second similarly positioned ends. The lamp is electrically connected to the positive and negative terminals of the vehicle battery via a switch for energizing the high beam filament momentarily in a "flash to pass" mode while the low beam filament remains energized. The filaments are wired with the first end of the low beam filament and second end of the high beam filament being connected to the negative terminal of the battery and the first end of the high beam filament and second end of the low beam filament connected to the positive terminal of the battery to avoid arcing between filaments which occurs in prior art lamps of this type during initial operation of the low beam filament and "flash to pass" operation of the high beam filament.
