Abstract: A system and method involve driver-side high beams to be selectively deactivated for oncoming traffic. It is intended to allow passenger-side high beams to continue operation to preserve the driver's peripheral vision. The driver's side high beam is manually controlled by a separate switch.

This produces a situation in which the oncoming driver is no longer blinded, but the vehicle driver still maintains the extended vision of the high beam on the left-hand side of the vehicle.
