Abstract
A control apparatus for a dazzle-free reflection mirror of a vehicle is disclosed. The control apparatus is provided with a rear light sensor and a circuit for driving the reflection mirror into a dazzle-free operation in accordance with the intensity of the rear light detected by the rear light sensor when a light switch is turned on. The control apparatus is further provided with a mirror adjusting device for adjusting the reflection angle of the reflection mirror and a detecting circuit for detecting the adjusting operation of the mirror adjusting device. When the detecting circuit detects the adjusting operation, the dazzle-free operation of the reflection mirror is disabled even if intensive light is incident to the reflection mirror from the rear of the vehicle.
