Abstract
A vehicle light control device includes: a power unit capable of supplying electric power to a vehicle light unit; a wheel speed detecting circuit detecting a wheel speed of a vehicle so as to generate a wheel speed signal indicating the wheel speed of the vehicle; and a control unit determining, based on the wheel speed signal, whether the wheel speed of the vehicle is lower than a predetermined wheel speed threshold when a rotational speed of an engine of the vehicle reaches a predetermined rotational speed threshold, and operable to enable the power unit to output a low duty-cycle voltage serving as electric power to a vehicle light unit upon determining that the wheel speed of the vehicle is lower than the predetermined wheel speed threshold.
