Abstract: A light apparatus has a first source of light, a first surface for causing light transmitted therethrough from the first source to have a first color, a second source of light, a second surface for causing light transmitted therethrough from the second source to have a second color, and a coating on the second surface to prevent light from the first source that is transmitted through the first surface from passing through the second surface.
Abstract: According to the invention, a single headlamp is provided to selectively project a first color light, a second color light or a desired blend thereof. Preferably, a clear bulb contains a second bulb with a yellow light transmitting surface. Each bulb has a filament light source which can be selectively powered to produce white and yellow light, with the latter being effective for penetration of fog, dust, smoke, etc. with the lamp used on a moving vehicle.
