A safety light for vehicles, particularly small recreational vehicles such as all terrain vehicles, which is one or more light strips entwining the whip which supports the vehicle's pennant or flag. This invention can normally show light in a color which matches the color of the recreational vehicle. When the vehicle operator applies the brakes, the light entwining the whip changes to red to warn that the vehicle is braking. When the vehicle is overturned, or at the operator's command in the event of another emergency, the lights entwining the whip can be made to oscillate rapidly back and forth between the red and the other color that is normally shown. In this way the vehicle displays a clear emergency signal.
