Claims
- 1. A flashing light warning system for mounting on the roof of a vehicle comprising, in combination, at least four individual light assemblies each including a light source and a beam-shaping lens, said lens portion of each of said light assemblies being rotatable about a generally vertical axis for producing generally horizontal light flashes in different radial directions, said light assemblies being mounted in a common housing in generally side-by-side relation spaced transversely across the width of a vehicle roof on which said housing is mounted, certain of said lenses being oriented in different rotational positions with respect to other lenses to produce a predetermined sequence of flashes from different ones of said light assemblies, each of said lenses being interconnected with one another to maintain the relative orientation between them during rotation thereof, and motor drive means for conjointly rotating said lenses.
- 2. A flashing light warning system as defined in claim 1 comprising at least three light assemblies mounted in a left hand section of said housing and at least three light assemblies mounted in a right hand section of said housing, certain of the lenses in the left hand housing section being oriented in different rotational positions with respect to each other and certain of the lenses in the right hand housing section being oriented in different rotational positions with respect to each other, and the lenses in said left hand housing section being rotationally positioned in a manner symmetrical to the lenses in said right hand housing section.
- 3. A flashing light warning system as defined in claim 1 comprising at least three light assemblies mounted in a left hand section of said housing and at least three light assemblies mounted in a right hand section of said housing, the rotational position of each of the six lenses being advanced a predetermined increment from an adjacent lens so that said lenses produce a series of light flashes seriatim beginning at one end of the plurality of light assemblies and progressing to the other end thereof.
- 4. A flashing light warning system as defined in claim 1 comprising at least three light assemblies mounted in a left hand section of said housing and at least three light assemblies mounted in a right hand section of said housing, said left and right hand housing sections being separated by a center housing section, each of the lenses mounted in said left hand section of the housing being interconnected for conjoint rotation by a first set of gears, each of the lenses mounted in said right hand section of the housing being interconnected for conjoint rotation by a second set of gears, and said drive means including means interconnecting said first and second sets of gears.
- 5. A flashing light warning system as defined in claim 4 where each lens is mounted on its own individual lens gear which is rotatable about a vertical axis, said lens gears being spaced from each other and interconnected by a plurality of idler gears disposed between adjacent lens gears in driving relation therewith.
- 6. A flashing light warning system as defined in claim 1 where each of said rotatable lenses has indicator means associated therewith to facilitate setting the rotational positions of said lenses relative to one another.
- 7. A flashing light warning system as defined in claim 1 where said motor drive means comprises a single drive motor for conjointly rotating all of said lenses.
- 8. A flashing light warning system as defined in claim 1 where each lens is fixedly mounted on an individual lens gear, interconnecting means including a plurality of idler gears interconnecting said lens gears for conjoint rotation, and said lens gears being adjustably mounted relative to one another to permit adjustment of the rotational position of any selected lens relative to the other lenses thereby permitting variation of the flash sequence.
