In order to facilitate the operation of the driver, a rear view mirror must be installed in the vehicle. Since the external rear-view mirrors positioned at both sides of the automobile can only see both sides of the automobile body and can not completely collect all information around the automobile body, the regions which can not be observed from the external rear-view mirrors of the automobile are dead zones of the external rear-view mirrors. If the automobile and the vehicle run in parallel, the automobile is in the blind area range of the outer rearview mirror and is not easy to be observed in the outer rearview mirror, and great potential safety hazards are generated. It is very necessary to set up blind area suggestion subassembly in the outside rear-view mirror of car. The blind area prompt component can help a driver to know whether a vehicle is in the blind area of the outer rearview mirror or not, so that the visual blind area of the driver is reduced, and the driving safety is ensured.
However, the existing automobile blind area prompting lamp has the condition that the brightness of the prompting pattern is not uniform. If the design of the blind area prompt pattern is slightly complicated, the brightness of the blind area prompt pattern is more easily uneven, so that a driver cannot easily observe whether a vehicle enters the blind area of the vehicle body, and the function of reminding the driver that the vehicle exists in the blind area cannot be realized.
