A wing mirror, also known as a side mirror, is a reflective device mounted on the exterior of a vehicle, typically on the driver's and passenger's sides. Its primary function is to provide the driver with a view of the area behind and beside the vehicle, helping to enhance safety while driving. Wing mirrors can be manually adjusted or equipped with electronic controls for convenience. Many modern wing mirrors also include additional features such as turn signal lights, heating elements for defrosting, and blind spot monitoring systems. These enhancements improve visibility and reduce the risk of accidents, making wing mirrors an essential component of vehicle design.
