Gentex Announces Additional Range Rover Automatic High-Beam Assist (SmartBeam(R)) Programs

ZEELAND, MI--(Marketwire - July 16, 2009) - Gentex Corporation (NASDAQ: GNTX), the leading supplier of automatic-dimming rearview mirrors to the worldwide automotive industry, has announced that it is supplying auto-dimming mirrors with its Automatic High-Beam Assist (SmartBeam) feature for the 2010 Range Rover Sport and Discovery 4 sport utility vehicles. The 2010 models will be available worldwide beginning in late summer 2009.

In addition to offering interior auto-dimming mirrors, both the Sport and the new Discovery 4 models feature Gentex's SmartBeam High-Beam Headlamp Assist as an option. SmartBeam uses a miniature camera-on-a-chip combined with algorithmic decision making to automatically turn a vehicle's high beams on and off according to surrounding traffic conditions. The system is designed to maximize a vehicle's forward lighting and to eliminate the repetitive and sometimes burdensome task of turning the high beams on and off.

"Earlier this year we announced that Land Rover had introduced SmartBeam on its new Range Rover model, and we are very pleased to see Land Rover expanding the availability of this active safety technology product across its vehicle line," said Enoch Jen, Gentex Senior Vice President.

Gentex has been shipping its SmartBeam feature to various automakers since 2004. More than a million of these imager systems are in operation on vehicles throughout Europe and North America, making Gentex the leading provider of automotive-grade camera-based active safety systems.

Founded in 1974, Gentex Corporation (NASDAQ: GNTX) is an international company that provides high-quality products to the worldwide automotive industry and North American fire protection market. Based in Zeeland, Michigan, the Company develops, manufactures and markets interior and exterior automatic-dimming automotive rearview mirrors that utilize proprietary electrochromic technology to dim in proportion to the amount of headlight glare from trailing vehicle headlamps. Many of the mirrors are sold with advanced electronic features, and more than 96 percent of the Company's revenues are derived from the sale of auto-dimming mirrors to nearly every major automaker in the world.
