Vehicle fit: compatible with 1999-2007 Ford F250 F350 F450 F550 Super Duty, 2001-2005 Ford Excursion
Telescoping & turn signal: unlike non-adjustable mirrors, these trailer tow mirrors effectively extend line of sight to provide a larger viewing area; and turn signal makes it easy to spot to increase safety when turning or changing lanes
Power heated: this plane mirror can remove the frost and mist to keep it clear when driving in rain and snowfall weather
Simple installation: directly connect to existing wiring harness with no drilling needed and all mounting positions align with your vehicle to ensure a precise match; sold as a pair, including both LH (Driver Side) & RH (Passenger Side)
Note: if your vehicle doesn't have the listed functions(such as turn signal), it might not function well; professional installation would be highly recommended
