ABSTRACT:
A turn signal control circuit has a power source, left and right turn signal inputs, a speed detection input and circuitry for conditioning the power source voltage and current as well as the input signals for proper operation. When a turn signal switch provides an input signal to a logic controller, the circuit begins flashing the respective turn signal. Upon release of the switch, a microprocessor reviews the vehicle speed by way of a speedometer input line and references a lookup table to determine the proper distance at which to turn off the signal. Generally, the faster the vehicle is travelling, the longer the turn signals are left on. Various manual cancellation options are also available to the motorcycle operator. A four-way flasher sysem is operated by simultaneously pushing the two turn signal switches, remaining on until both switches are again simultaneously pressed. Furthermore, an electrical "bulb out" detection system warns the motorcycle operator of a burned out light bulb and operates signals at a substantially slower rate when a bulb is burned out.
