Abstract

Abstract A combination warning light and emergency flasher apparatus includes a pair of white light projecting means, cooperatively mounted on a housing such that the beam of light projected by each light projecting means is in an opposing ''''off-center'''' downward direction, and an emergency light projecting means having a red translucent lens covering. A control circuit includes an electronic triggering means operable to selectively cause either the pair of white light projecting means to alternately flash bright and dim or cause the second emergency light projecting means to flash bright and dim.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 152 words
In a warning light apparatus for mounting on a vehicle consisting of: a rectangular housing having a flat surface and a longitudinal axis extending along the length of said housing, at least a pair of light mounting seats located along said longitudinal axis of said flat surface, a first and a second light source rigidly mounted on said light mounting seats along said longitudinal axis, said first light source oriented to project a beam of illumination downward and to the side of an imaginary line drawn perpendicular to said longitudinal axis of said flat surface, said second light source oriented to project a beam of illumination downward and to the opposite side of said perpendicular line in a mirrored relationship to said beam of illumination of said first light source, a circuit means operable to continuously flash said first and second light sources from a fully illuminated condition to a dim condition.
Claim 2
Dependent Claim 152 words
In a warning light apparatus for mounting on a vehicle consisting of: a rectangular housing having a flat surface and a longitudinal axis extending along the length of said housing, at least a pair of light mounting seats located along said longitudinal axis of said flat surface, a first and a second light source rigidly mounted on said light mounting seats along said longitudinal axis, said first light source oriented to project a beam of illumination downward and to the side of an imaginary line drawn perpendicular to said longitudinal axis of said flat surface, said second light source oriented to project a beam of illumination downward and to the opposite side of said perpendicular line in a mirrored relationship to said beam of illumination of said first light source, a circuit means operable to continuously flash said first and second light sources from a fully illuminated condition to a dim condition.
Claim 3
Dependent Claim 34 words
A warning light apparatus according to claim 1, further comprising a manual stall switch in operable relationship to said circuit means, whereby either of said first or second light sources can be fully illuminated.
Claim 4
Dependent Claim 46 words
A warning light apparatus according to claim 2, further comprising a dimmer resistance selectively placed in series with said first and second light sources functioning to reduce the illumination of said first and second light sources when a second vehicle is approaching from the opposite direction.
Claim 5
Dependent Claim 213 words
A combination warning light and emergency flasher for mounting on a vehicle such as a locomotive, consisting of: a rectangular housing having a flat surface and a longitudinal axis extending along the length of said housing, a plurality of light mounting seats located along said longitudinal axis of said flat surface, a first and a second white light source rigidly mounted adjacent each other on two said light mounting seats along said longitudinal axis, said first white light source oriented to project a beam of illumination downward and to the side of an imaginary line drawn perpendicular to said longitudinal axis of said flat surface, said second white light source oriented to project a beam of illumination downward and to the opposite side of said perpendicular line in a mirrored relationship to said beam of illumination of said first light source, a third emergency light source mounted on a third light mounting seat operable to project a colored beam of illumination in a parallel relationship to said longitudinal axis of said flat surface, and a circuit means operable to selectively alternate said first and second white light sources from a fully illuminated condition to a dim condition, or flash said third emergency light source from a fully illuminated condition to a dim condition.
Claim 6
Dependent Claim 213 words
A combination warning light and emergency flasher for mounting on a vehicle such as a locomotive, consisting of: a rectangular housing having a flat surface and a longitudinal axis extending along the length of said housing, a plurality of light mounting seats located along said longitudinal axis of said flat surface, a first and a second white light source rigidly mounted adjacent each other on two said light mounting seats along said longitudinal axis, said first white light source oriented to project a beam of illumination downward and to the side of an imaginary line drawn perpendicular to said longitudinal axis of said flat surface, said second white light source oriented to project a beam of illumination downward and to the opposite side of said perpendicular line in a mirrored relationship to said beam of illumination of said first light source, a third emergency light source mounted on a third light mounting seat operable to project a colored beam of illumination in a parallel relationship to said longitudinal axis of said flat surface, and a circuit means operable to selectively alternate said first and second white light sources from a fully illuminated condition to a dim condition, or flash said third emergency light source from a fully illuminated condition to a dim condition.
Claim 7
Dependent Claim 37 words
A combination warning light and emergency flasher according to claim 4, further comprising a manual stall switch in operable relationship to said circuit means, whereby either of said first or second light sources can be fully illuminated.
Claim 8
Dependent Claim 51 words
A combination warning light and emergency flasher according to claim 5, further comprising a dimmer resistance selectively placed in series with said first and second white light sources functioning to reduce the illumination of said first and second white light sources when a second vehicle is approaching from the opposite direction.
Claim 9
Dependent Claim 43 words
A combination warning light and emergency flasher according to claim 4, further comprising a circuit means in operable relationship to the conventional headlights of the vehicle to automatically extinguish said conventional headlights whenever said third emergency light source is in an energized condition.
Claim 10
Dependent Claim 50 words
A combination warning light and emergency flasher according to claim 4, further comprising a pressure switch responsive to a predetermined level of brake line pressure of a vehicle and in operable relationship to said circuit means to extinguish all sources of white light and energize said third emergency light source.
