The safety beacon of the present invention includes an arrangement of light emitting diodes (LEDs) controlled by a controller circuit and preferably powered by a rechargeable battery source. The rechargeable battery source will recharge when coupled to any appropriate power source, including a power outlet within a vehicle and a conventional wall power outlet. Further, when coupled to such a power source, the safety beacon will draw power for operation from the power source without using the battery source. The safety beacon encases the LEDs with a base preferably of a hard rubber casing and an outer housing forming a lens and preferably made of a high impact clear plastic. The safety beacon includes a port and connecting cable so that multiple safety beacons can be strung together. In such a configuration, the multiple safety beacons are configured to share power with all safety beacons within the chain. Preferably, the safety beacon includes a magnet within its base for affixing the safety beacon to metal surfaces, such as the surface of an automobile. The safety beacon also preferably is operated either manually or by a remote control device.
