Although its use may not be frequent, a safety light is a very handy tool to keep in any vehicle, truck or marine craft. This Super Force Flashing Signal Light operates much like any other warning light, operating from a simple 12V power source. Unlike some other lights however, this unit includes a tough, refractive lens to assist in the dispersion of light, rather than other products which might simply use a rotating reflector. This allows the light to cover a much larger area, thus potentially giving other vehicles earlier notice of your signal. This light features a powerful magnetic base, and will easily attach to any metal surface without fuss.
