A signaling device intended to be worn by a moving user such as a rider of a two-wheel vehicle providing improved visibility on the part of other road users through the provision of a light source at a greater height than is conventional for such vehicles comprises an accelerometer taking measurements along three orthogonal axes, a rechargeable battery pack, a first light source, wireless communication means for transmitting an alert signal and a control unit which activates the light source above a particular deceleration or braking threshold, activates the communication means at a higher deceleration or accident threshold and activates the communication means when a number of switchovers between acceleration and deceleration is equal to or higher than a third threshold.
