    Headlight glare and your rear view mirror make a dangerous combination. Eliminate this volatile mixture with the Gentex K21 Auto-Dimming Rear View Mirror.

    The K21 Auto-Dimming Rear View Mirror detects dangerous rear-approaching light and eliminates it with "intelligent" circuitry. What's more, less glare means less eyestrain and driver fatigue.

    As if that weren't enough, the K21 Auto-Dimming Rear View Mirror comes with a self-calibrating digital display compass. The mirror even has an exterior thermometer that displays temps and ice warnings.

    The windshield-mounted mirror comes complete with detailed installation instructions and all necessary hardware - perfect for the experienced do-it-yourselfer or professional installer with some wiring required. And, the Auto-Dimming Rear View Mirror comes with 3-year / 36, 000 mile warranty. See what a difference the K21 Auto-Dimming Rear View Mirror can make.
