Abstract
Abstract A sealed beam headlight has an additional source of light located outside the line of the main light beam but located adjacent a colored disc in the lens of the light. A separate circuit controls the additional source of light and is connected to the brake pedal of an automobile. The headlight accordingly not only provides forward illumination when required, but also signals operation of the braking system of the vehicle to those who can see the front of the vehicle.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
143 words
A sealed beam headlight having a first parabolic reflector with a horizontally extending axis, a first light source carried by said reflector and located adjacent said axis, and a lens integrally formed with said reflector, characterized by a second light source carried by a second parabolic reflector located away from the axis of said first reflector, and a colored insert in said lens located away from the axis of said first reflector, said second light source being located in the axis of said second reflector adjacent to the insert in the lens, said second parabolic reflector substantially surrounding said second light source and shielding said colored insert from light emitted by said first light source, said second light source being connected to its own power terminal for connection in a circuit other than a circuit in which said first light source is connected.
Claim 2
Dependent Claim
143 words
A sealed beam headlight having a first parabolic reflector with a horizontally extending axis, a first light source carried by said reflector and located adjacent said axis, and a lens integrally formed with said reflector, characterized by a second light source carried by a second parabolic reflector located away from the axis of said first reflector, and a colored insert in said lens located away from the axis of said first reflector, said second light source being located in the axis of said second reflector adjacent to the insert in the lens, said second parabolic reflector substantially surrounding said second light source and shielding said colored insert from light emitted by said first light source, said second light source being connected to its own power terminal for connection in a circuit other than a circuit in which said first light source is connected.
