Abstract
A control apparatus for a reflection mirror of a vehicle is disclosed. The control apparatus is provided with a rear light sensor, an exterior light sensor and a circuit for driving the reflection mirror into a dazzle-free condition when it is detected by the sensors that an intensive rear light is incident from the rear of the vehicle and the exterior of the vehicle is dark. The control apparatus is further provided with a delay circuit which delays driving the reflection mirror into the dazzle-free condition for a predetermined interval of time after the exterior light sensor detects that the exterior of the vehicle is dark. The exterior light sensor may be a switching circuit which switches on and off front light bulbs of the vehicle. The control apparatus is still further provided with a delay circuit which keeps the dazzle-free condition for a predetermined interval of time even after the rear light sensor detects that the rear of the vehicle is dark.
