Glare has been a particular concern for many years since new vehicles have brighter headlights that can sometimes cause discomfort or even temporarily blind other drivers.
Night driving is difficult and dangerous due to the blinding glare of headlights from oncoming traffic. Headlamps that satisfactorily illuminate the road ahead without causing glare have long been sought. The first solutions involved resistance-type dimming circuits, which decreased the intensity of the headlamps.
Discomfort glare is a psychological sensation caused by high brightness (or brightness contrast) within the field of view, which does not necessarily impair vision. [2] In buildings, discomfort glare can originate from small artificial lights (e.g. ceiling fixtures) that have brightnesses that are significantly greater than their surrounding.
BMW Night Vision introduced in 2005 on the BMW 7 Series (E65). This system processes far infrared radiation, which minimizes non-essential information placing a greater emphasis on pedestrians and animals, allows for a range of 300 meters or nearly 1,000 feet, and avoids "dazzle" from headlights, road lights and similar intense light sources.

The "city light" terminology for front position lights [31] derives from the practice, formerly adhered to in cities like Moscow, London and Paris, of driving at night in urban areas using these low-intensity lights rather than the vehicle's headlights.
glare from bad lighting is a public-health hazard—especially the older you become. Glare light scattering in the eye causes loss of contrast and leads to unsafe driving conditions, much like the glare on a dirty windshield from low-angle sunlight or the high beams from an oncoming car."
The lights of a padiddle. Padiddle, alternatively spelled pediddle or perdiddle, is a night driving game where players look for vehicles with a single burnt-out headlight or brake light, the word padiddle being a slang term for such a vehicle. The term popeye is also used, due to it resembling a missing or squinting eye.
However, the bright headlights have given rise to complaints about glare. [10] HID lamps are used in high-performance bicycle headlamps, as well as flashlights and other portable lights, because they produce a great amount of light per unit of power. As the HID lights use less than half the power of an equivalent tungsten-halogen light, a ...
