Abstract: If the brightness of the reversing lamp cannot change with the outside world,it only plays a signal role and cannot achieve the effect of illumination.This paper redesigns the circuit of the reversing lamp.When the car enters the reversing gear,if the external light is sufficient,the brightness of the reversing lamp will not increase and the reversing lamp only acts as a signal.When the external light is insufficient,the brightness of the reversing lamp will enhance,which has dual functions of illumination and signal,thus increasing the safety of reversing.

Key words: brightness, adjustment, reversing lamp
