The present invention is a 
signaling system for a motorcycle or bicycle providing a light indication to other motorists. An indication mechanism is attached to a garment of the rider. The indication mechanism has at least two banks of LEDs arrays and a 
wireless radio receiver. A 
signal interface is linked to the wiring 
system of the motorcycle light 
system. The 
signal interface intercepts signals transmitted on the wiring 
system of the motorcycle light system. The system also includes a 
wireless radio 
transmitter in communication with the 
signal interface. When the signal interface detects a signal sent through the wiring system of the motorcycle, the signal interface sends a signal via the 
transmitter to the 
receiver of the indication mechanism. The indication mechanism then illuminates the appropriate 
bank of LED arrays to provide a light indication to warn other motorists. In an alternate embodiment of the present invention, the indication mechanism may be worn by a cyclist. The signal interface may communicate with a sensing device which receives signals from a braking mechanism of the bicycle. When the braking mechanism is actuated, the sensing device senses the braking action and sends a signal via the 
transmitter to the 
receiver of the indication mechanism, which in turn illuminates the LED arrays. Alternately, rather than utilizing a signal interface, the indication mechanism may include an 
accelerometer to detect deceleration of the bicycle.
