An arrangement comprising a main body having a head continuous with a grip, an LED housed in the main body for emitting warning light from within the grip, a light bulb housed in the main body for emitting warning light through glass disposed in at the front end of the head, a light emission controller for controlling the emission of light from the LED and light bulb, and a percussion imparting member attached to the head for breaking a window glass in a car. This arrangement makes it unnecessary to secure a space for installing both a hammer and an emergency signal instrument in a car.
