1. A motor cycle license plate holder comprising:
- one or more LED warning lights; and
electronic circuitry comprising;
a dual variable reluctance sensor circuit supplied with a wind turbine-generated A.C. signal for converting said A.C. signal to a rectangular waveform representative of turbine rotor rpm (revolutions per minute) suitable for input to a microprocessor;
a microprocessor configured to receive said rectangular waveform and to detect deceleration of the motorcycle by determining whether rotor rpm is decreasing and to cause illumination of the one or more LED warning lights if the rotor rpm decreases more than a selected amount over a selected time interval;
a battery; and
a battery charging circuit supplied with power derived from a wind turbine generated A.C. signal and configured to charge said battery.
