A Matched Pair for a Consistent Look
Replacing only one side mirror can leave your vehicle with two noticeably different exterior components. The Fit System 1600B solves that problem by supplying both driver and passenger mirrors together.
The black finish works well on a wide variety of vehicle styles, from daily drivers and work trucks to older project vehicles and custom builds.
And yes, both sides matching is still a thing. Your car doesn’t need to look like it lost a fight with the parts counter.
Flat Glass for a Familiar Reflection
The 1600B uses flat mirror glass measuring 5-7/8″ x 3-7/8″.
Flat glass provides a conventional reflected image without the intentional wide-angle effect of convex mirrors. This makes it different from panoramic and blind-spot-style mirrors designed specifically to expand the viewing area.
Proper mirror adjustment remains important regardless of mirror style. Set both mirrors while the vehicle is stationary and verify your rearward visibility before driving.
Universal Door-Mount Application
The 1600B is designed for compatible door-mounted exterior mirror applications.
Because vehicles use different door structures and mounting configurations, installation requirements can vary. Before purchasing, compare your original mirror’s mounting arrangement with the 1600B and verify that there is sufficient clearance for the replacement housing.
Potential applications include compatible:
- Cars
- Pickup trucks
- Light trucks
- Custom vehicles
- Project vehicles
Installation
The 1600B is designed as a universal replacement-style mirror for compatible door-mount applications.
