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. During use, when an oncoming vehicle approaches, the activation of the switch allows the driver to deactivate only the driver side high beam while the passenger side high beam remains activated. 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.
