Provided is a signaling device for a traffic accident to prevent a secondary road accident, which can prevent a secondary accident on the road by rapidly informing a forward traffic situation at the lowest cost by a relatively simple structure. The signaling device of the present invention comprises indicators (10) installed in the median strip of the road at regular intervals and each including a sound sensor (20) for detecting the horn sound of a vehicle, an LED output unit (12) provided on the front thereof, a circuit unit (20) for transmitting a detection signal of the sound sensor to the LED output unit, and a solar panel (20) and a storage battery (21) as power supply means. Each indicator (10) has a transceiver (14). Therefore, when the horn sound is detected by one sound sensor, the front and rear indicators sequentially output the same warning to the LED output units. |
