A hazard marker kit has several components including a hazard light, a base for supporting the light in different angular orientations on different surfaces, a translucent cone, and a staff with attached pennant. The hazard light is housed within a disc shaped high impact plastic housing, an upper portion of which is transparent. A plurality of LEDs are circularly disposed proximal to the side of the upper portion. A ring counter provides signals to transistors that sequentially drive the LEDs. Excitation provided to the ring counter is controlled to cause a desired current through the LEDs to simulate a rotating beacon, a flashing beacon or a continuous light. |
