Abstract: A warning barricade apparatus for restricting pedestrian and vehicular traffic and having an increased ability to minimize dislocation of an associated lighting unit upon vehicular impact, while also facilitating removal of the lighting unit for relocation and battery replacement. The warning barricade apparatus comprises a barricade member, an associated lighting unit, a lighting unit sleeve, and an overlaying member. The lighting unit sleeve comprises opposing retaining wall members, which define a lighting unit retention region. The overlaying member covers at least a portion of the lighting unit retention region, and preferably conforms to at least a portion of the lighting unit contour. Upon insertion of the lighting unit into the lighting unit retention region, the overlaying member comes into contact with or partially covers at least a portion of the lighting unit, and a securing member, such as a bolt, anchors the lighting unit to the lighting unit sleeve.

Abstract: The present disclosure is directed to an apparatus for extending useful life of barricade warning light. The apparatus comprises a light source; a battery having an output voltage; and an oscillator circuit connected to the battery. The oscillator circuit drives the light source in either a first or alternate mode, wherein the first mode the light source flashes within a desired flasher frequency range and the alternate mode the light source is continually illuminated. The oscillator biased such that the oscillator circuit automatically switches from the first mode into the alternate mode at an optimal value for the battery output voltage. A method for extending useful life of barricade warning light is also disclosed.

Abstract: The present invention is directed to a barricade light control switch apparatus for operating a battery powered barricade light unit. The apparatus comprises a light unit housing, light source, battery, and circuit means for controlling operation of the light source, and a reed switch. A magnet retained by a magnet carrier is positionable in either of two positions and controls operation of the reed switch. When the magnet carrier is in a first position the magnet is positioned in proximity to and closes the reed switch. When the magnet carrier is in a second position the magnet is positioned away from and opens the reed switch. Retention means preclude unintended movement of the magnet carrier. A method for controlling a barricade light unit is also disclosed.
