Abstract: A self-contained hazard marker which is easily deployed and highly visible. The hazard marker utilized an elevated collapsible illumination device which utilizes LEDs mounted to a flexible printed circuit board in a fashion that allows the circuit board to be formed into a tubular shape with the LEDs on the outer surface of the tube in a fashion that disperses the light in a 360 degree pattern. These LEDs can be illuminated in various patterns thereby producing various effects. They can produce a rotating light effect, a blinking light effect, a strobe effect and a simulated flare. The elevated illumination device is also collapsible into the body (protection chamber) of the marker in the event a vehicle is driven over the marker. The marker has a ramp shape to it that starts at ground level and extends to the top of the unit. This shape inherently prevents the unit from lateral movement when impacted.

Abstract: A self-contained hazard marker which is easily deployed and highly visible. The hazard marker utilized a pop-up type of illumination device which utilizes LEDs. These LEDs can be illuminated in various patterns thereby producing various effects. They can produce a rotating light effect, a blinking light effect, a strobe effect and a simulated flare. The pop-up illumination device is also retractable into the body of the marker in the event a vehicle is driven over the marker. The marker also contains deployable securing devices which prevent the marker from being moved horizontally from its operative position.

Abstract: A highway hazard marker 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.
