ABSTRACT:
A system and method for reducing vehicle window (e.g., windshield and/or backlite) visible light transmission when high beams are detected. In certain example embodiments, a detector detects the presence of a light source above certain luminescent threshold. A controller then reduces the visible light transmission of a windshield and/or backlite via an electrochromic process and/or by using electrodes to apply a voltage across a gas-filled chamber for example. The visible light transmission is restored when the controller determines that the light source detected has dropped below the threshold luminescence or has disappeared.
