A vehicle headlight has a segmented light guide device in which segments are selectively controlled to operate in an output state that reduces glare to oncoming vehicle drivers. Vehicle sensors and controller circuitry are used to identify areas of glare removal in the light pattern of the headlight and control the corresponding segments in the light guide device to operate in a selected light output state that reduces glare. The segments can be operated in a focused output state for vehicle driver visibility, or in a scattered output state to reduce glare. The segments can be operated in a clear or transparent output state for vehicle driver visibility, or in a reflected output state to reduce glare. Reflected light can optionally be re-directed. The light guide device can employ bi-stable liquid crystal shuttering or liquid crystal switchable mirror technology.
