Power side-view mirror
A power side-view mirror (power side mirror, power wing mirror, or simply power mirror) is a side-view mirror equipped with electrical means for vertical and horizontal adjustment from the inside of the automobile.
The glass of a power mirror may also be electrically heated to keep it from fogging or icing.{{cite book|title=How to Rebuild and Modify Your Muscle Car|author=Scott, J.|publisher=MotorBooks International|isbn=9781610590181|url=https://books.google.com/books?id=g8SWg4ULPJMC&pg=PA166|page=166|access-date=5 July 2015}}
Increasingly, power side mirrors incorporate the vehicle's turn signal repeaters. There is evidence to suggest mirror-mounted repeaters may be more effective than repeaters mounted in the previously predominant fender side location.

Operation
Usually, a single control is used to control both left and right side mirrors. A mirror is selected by a switch or a knob. The mirror selector usually has a neutral position with no mirrors selected, to prevent accidental changes of the view. The position of the selected mirror is adjusted by a joystick, a four-way knob, or other type of position control.{{cite book|title=Today's Technician|author1=Hollembeak, B.|author2=Erjavec, J.|year=2002|isbn=9780766820999|url=https://books.google.com/books?id=UrugUxsVWncC&pg=PA373|page=373|access-date=5 July 2015}}{{cite book|title=The Car Care Book|author=Haefner, R.|date=2008|publisher=Cengage Learning|isbn=9781111780821|url=https://books.google.com/books?id=SScEAAAAQBAJ&pg=PA267|page=267|access-date=5 July 2015}} In luxury designs, power mirror settings may be memorized together with settings of power seats.
