Abstract: A novel compact and portable lighting system can be used for both mobile and immobile vehicles. The lighting system can act both as auxiliary lighting and as back-up lighting for standard vehicle light systems. This novel system includes an auxiliary portable power source such as a battery and a control box which can be mounted on the inside of a window. The lighting assemblies connected through the control box can include any combination of headlights, brake lights, reverse lights, signal lights, hazard lights or other useful lights. The lighting assemblies connected to the control box can be enabled independently of each other. The frame upon which the lights are mounted is adjustable in size so as to be able to fit any sized vehicle. A preferred means to secure this novel portable lighting system is with magnetic suction cups so that the invention can be secured to both metallic and nonmetallic surfaces. This enables rapid placement and easy removal of the lighting system as desired.

A semiconductor timer circuit is also configured to be energized when brakes are applied. It produces a time out signal which activates a predetermined duration after brakes are applied and which is responsible for causing the CHMSL to remain continuously activated. The outputs of the oscillator and timer circuits are combined at a semiconductor switch which drives the CHMSL.

Abstract: This invention relates to a signal warning light device designed to be mounted on the roof of an emergency vehicle. Normally this device, in use, would appear to be a frame holding a line of lights across the top of the vehicle. However, at the scene of an emergency, under control of the driver, bars pivoted at the two ends of the frame would be automatically swiveled upward. When raised fully, the bars would appear vertical and with its vertical array of lights woudl provide approaching drivers with an advanced warning. By limiting the movement of one bar to an acute angle and not fully raising the other bar the effect of a pointing arrow or spear head would be obtained. Thus by selectively controlling the bars to be raised, traffic could be directed to proceed left or right or if the both bars were raised partially, signals to stop, slow as well as right and left may be given. Sequential flashing of the bar mounted lights would emphasize the message when directed toward the "point".

Abstract: A protective guard is provided for a school bus. A series of telescoping members retracts along the front of the bus, and are in a compact form when the bus is moving. When the school bus stops two of the members telescope outwardly in series and extend across the lane of oncoming traffic. The members are so long and strong that any motorist attempting to pass the bus will damage his car. Flashing red lights are mounted on the extended members. The members are extended and retracted by a lead screw. The lead screw, when it extends the telescoping members, first drives the innermost member outwardly and away from the other movable member. The lead screw then engages the other movable member and drives it outwardly and it carries the innermost member to its ultimate extended position.
