Abstract: A warning device comprising a lightbar, a programmable chip for controlling LED lights, a controller, and a rechargeable battery. The lightbar is removably coupled to the emergency vehicle or another object such as a road block, where a dangerous situation exists, to warn persons of a hazard. Rechargeable batteries are recharged by solar panels on the lightbar. Rechargeable batteries are used to power the warning device. The programmable chip for controlling the LED is linked wirelessly to the controller, a remote control. The lightbar may be activated by a remote control from inside or outside the vehicle or from a base station to perform a variety of tasks. Warnings may be transmitted from the lightbar using visual and audio signals. Visual signals may include flashing at various speeds and intensities in various colors, text messages and other warning signals to advise persons of dangers in an effort to promote safety.
