Door mirror

The present invention relates to a door mirror having a built-in lamp.

A lamp is built in the door mirror, and a technique is known in which the lamp illuminates the lower side surface of the vehicle door (see Patent Documents 1 to 4). A filament that emits light is used for the lamp, and the life of the filament itself is usually about several hundred to 1000 hours, and the lamp that has reached the end of its life causes non-lighting due to the filament running out. It is expected that the lamp will reach the end of its life during the long-term vehicle use period, in which case the lamp needs to be replaced. In particular, the life of the lamp tends to be shortened due to vibration and impact caused by running the vehicle, and the need for lamp replacement is high.
