Abstract
A compact, ambient light sensitive flashing warning light that is removably attached to a traffic control device to alert on-coming motorists and pedestrians of a roadway condition. A photocell is connected between a light bulb and a battery voltage source so that illumination of the bulb can be made dependent upon ambient light conditions. The warning light includes a tapered attachment leg that is sized to fit through a hole in the top of a conventional hollow traffic cone, such that the warning light is removably attached to the cone by friction. As an alternate embodiment, the warning light may be interfaced with a bracket that is adapted to be fastened to other traffic control devices such as a conventional wooden barricade.
Claims17
For attachment to a traffic control device, a warning light for alerting on-coming motorists and pedestrians to a roadway condition and comprising:
- a base above which a light bulb is supported;
- a source of supply voltage supported by said base and electrically connected to the light bulb to cause said bulb to be illuminated;
- a lens surrounding the light bulb above said base so that light is transmitted through said lens when the light bulb is illuminated;
- an attachment leg having a first end connected to said base and an opposite end to be connected to the traffic control device;
- and
- switch means electrically connected between said source of supply voltage and said light bulb, the first end of said attachment leg moving into physical contact with said switch means to control the operation thereof and the illumination of said light bulb when said first end is connected to said base.
In combination:
- a traffic cone having an opening formed therein;
- and
- a warning light to alert on-coming motorists and pedestrians to a roadway condition and comprising housing means, a light bulb supported within said housing means, a source of voltage to illuminate said light bulb, switch means electrically connected between said voltage source and said light bulb, a lens surrounding said light bulb and coupled to said housing means so that light from said bulb is transmitted through said lens, and an attachment leg projecting from said housing means, a first end of said attachment leg received within the opening of said traffic cone by which said warning light is attached to said traffic cone and the opposite end of said attachment leg physically contacting said switch means to control the operation thereof and the illumination of said light bulb.
For attachment to a traffic control device, a warning light for alerting on-coming motorists and pedestrians to a roadway condition and comprising:
- a base from which a light bulb is supported;
- a source of supply voltage electrically connected to said light bulb to cause said light bulb to be illuminated;
- a bracket having at least first and second arms, said first arm connected to said base and said second arm to be attached to the traffic control device;
- switch means electrically connected between said source of supply voltage and said light bulb, said switch means carried by said base;
- and
- means connecting the first arm of said bracket to said base and including an attachment leg, a first end of said attachment leg penetrating said base and moving into physical contact with said switch means to control the operation thereof and the illumination of said light bulb when said bracket and said base are connected together.
