Gentex Corporation 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.

Gentex is a major supplier of automatic-dimming rearview mirrors to the worldwide automotive industry.

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.
