Abstract

A method of reducing glare from oncoming vehicle headlights in a vehicle having a driver'"'"'s side, a passenger side, a front windshield and a steering wheel comprises the steps of: providing a glare reducing means such as SMART GLASS on the vehicle adapted to substantially transmit light and to substantially reduce light, the glare reducing means having a width less than 30 percent of the horizontal width of the vehicle'"'"'s front windshield such that the passenger side is uncovered; driving the vehicle on a surface that can have oncoming traffic; operating the glare reducing means while driving to substantially transmit light to allow a driver to see through the glare reducing means when there is no oncoming traffic with lit headlights approaching; operating the glare reducing means to substantially reduce light while driving to reduce glare when there is at least one oncoming vehicle with lit headlights approaching the driver; and repeating the substantially light transmitting and substantially light reducing steps by the glare reducing means while driving to accommodate varying oncoming traffic. The glare reducing means can be operated manually by a wireless ON/OFF switch attached to the steering wheel or automatically by a high-beam headlight control system on the vehicle. And it can be installed as an attachment in an existing vehicle or as original equipment in new vehicle.
