Abstract
A turn signal apparatus includes a heading indicator which provides a heading signal and a control circuit which provides a turn direction output signal. The turn direction output signal is chosen to indicate a turn direction in response to the heading signal and a corresponding turn direction input signal. The turn direction can be for a right turn, a left turn, or a neutral turn. A left or right turn indication can be changed to a neutral turn indication in response to the heading signal.
