ABSTRACT:
A vehicle turn signal and/or hazard light display is created by utilizing a pair of lamps mounted upon in or on the dash top cowl of a vehicle. The bulbs of each lamp include a filament having a V-shaped portion which, upon electrical energization of the filament, becomes incandescent and a like V-shaped light display is projected from the lamps toward and impinges upon the vehicle windshield and is thereat visible to the driver. The V-shaped portions of the lamp filaments are oriented to point "left" and "right," and thus when appropriately connected to the turn signal circuit, will display "left" and "right" signals upon the windshield, or both "left" and "right" signals simultaneously which is the universal "hazard" signal. Since vehicle windshields are multi-ply, the leftward and rightward pointing "V-shaped" displays are visible in pairs.
