Gentex is best known, however, as the pioneer of the electrochromic, automatic-dimming mirror industry.

Gentex has made nighttime driving safer for millions of drivers around the globe by providing the worldwide

automotive industry with mirrors that detect and eliminate dangerous rearview mirror glare. Gentex auto-dimming

mirrors are offered as standard or optional equipment on over 220 vehicle models around the world.

Gentex uses its proprietary, solution-phase electrochromic technology. We sandwich an electrochromic gel between two pieces of glass, each of which has been treated with a transparent, electrically conductive coating, and one with a reflector. 1. A forward-facing sensor recognizes low ambient light levels and signals the mirror to begin looking for glare. 2. A rearward-facing sensor then detects glare from the vehicles traveling behind you, sending voltage to the mirror's EC gel in proportion to the amount of glare detected. 3. The mirror dims in proportion to the glare and then clears when the glare is no longer detected. 4. The interior mirror's sensors and electronics control the dimming of both interior and exterior mirrors. When it comes to automotive safety, why take risks with inferior products? Gentex is the industry leader -- a tested, proven supplier. The Industry Pioneer Gentex pioneered the electrochromic (EC), auto-dimming mirror industry. In fact, we created it. For over 20 years, automakers looked for ways to eliminate rearview mirror glare, and not until we invented the world's first auto-dimming mirror did a viable technology exist. See our "Corporate Overview" section for more information.    Superior Manufacturing Because we literally invented the electrochromic mirror industry, we also had to develop the supply base, manufacturing techniques and testing methods. It was a long learning curve. But today, our experience, knowledge and hard work has paid off, because no other glare reduction mirror provider in the world can match our manufacturing capabilities - not in yields, quality or volume. Superior Quality No other EC mirror manufacturer in the world can match Gentex's product quality. Our proprietary EC technology has inherent, far-reaching advantages over competitive glare-reduction techniques. In addition, ours are the only mirrors to meet the worldwide automotive specifications for durability and visual acuity. 　 Safety and More There are many reasons to consider Gentex auto-dimming rearview mirrors. Not only do they increase driving safety by eliminating accident-causing glare, but they also provide car manufacturers with a cost-effective way to offer customers value-added electronic devices and other features. Increasing Driving Safety Why should you consider Gentex auto-dimming mirrors? Because rearview mirror glare causes accidents. It's that simple. Research shows that during nighttime driving, headlight glare from the vehicles traveling behind you can be blinding. Even once the source of the glare is removed, an after-image remains on the eye's retina that creates a blind spot you may not even know exists. Known as the Troxler Effect, this phenomenon increases driver reaction time by up to 1.4 seconds. At 60 mph, you'd drive over 123 feet before you even reacted to the danger in front of you. Auto-dimming mirrors make nighttime driving safer by detecting glare and automatically dimming to protect driver vision. Airbags, crumple zones and the like may help you survive a crash, but auto-dimming mirrors help you avoid one altogether. The Troxler Effect Study The Troxler Effect study was conducted by Dr. Alan Lewis, 55, a veteran researcher and Dean of the Michigan College of Optometry at Ferris State University in Big Rapids, Michigan. He spent 20 years as professor of physiological optics at the State University of New York and is often called upon to conduct optical experiments for business and industry. His Troxler Effect research has been published by the Society of Automotive Engineers and has been cited by Optometric Management Magazine and other journals. Auto-Dimming Mirrors...Active, Crash Avoidance Safety Features Consumer Demand Another reason to consider auto-dimming mirrors is consumer demand. Consumer research conducted by a internationally recognized automotive research firm found that 90 percent feel auto-dimming mirrors increase driving safety, and 80 percent believe that both interior and exterior mirrors should be offered on vehicles like their own. Vehicle Content Upgrades Gentex auto-dimming mirrors also allow automotive manufacturers to easily upgrade a vehicle's electronic-features content while differentiating it from the competition. In addition to the auto-dimming function, Gentex mirrors can come with a variety of value-added electronic features, including external-temperature readouts, compass displays, remote keyless entry receivers, tire-pressure monitoring displays, headlamp control, LED map lamps and more. This allows manufacturers to incrementally add electronic features without costly vehicle-interior redesigns. Vehicle content can also be upgraded by adding exterior auto-dimming mirrors. Gentex manufactures flat, convex, aspheric and thin-glass exterior auto-dimming mirrors, which when combined with an internal mirror, allow manufacturers to provide two and three-mirror auto-dimming systems.

The mirrors made by Gentex  U.S.A., We import the Gentex auto dimming mirrors from US directly and come with Three year warranty.

The above car models are readily able to install just by attachment.

2.Windshield Non-Wedge Models
Car models with mirror on wind shield, but do not have the universal wedge style button standard must carefully detach original mount with knife blade. After detachment, use professional glue to attach the bracket(we can provide the 730-2023 kit for free, which including professional glue). Once dried, install the mirror. Or, if you have a mirror mounted on the car ceiling, you may just detach the original and install this mirror on your wind shield.
