A headlamp is a lamp, usually attached to the front of a vehicle such as a car, with the purpose of illuminating the road ahead during periods of low visibility, such as night or precipitation. While it is common for the term headlight to be used interchangeably in informal discussion, headlamp is the technically correct term for the device itself, while headlight properly refers to the beam of light produced and distributed by the device.
Modern headlights are electrically operated, positioned in pairs, one or two on each side of the front of a car. A headlight system is required to produce a low and a high beam, which may be achieved either by an individual lamp for each function or by a single multifunction lamp. High beams (called "main beams" or "full beams" or "driving beams") cast most of their light straight ahead, maximizing seeing distance, but producing too much glare for safe use when other cars are present on the road. Because there is no especial control of upward light, high beams also cause backdazzle from fog, rain and snow due to the retroflection of the water droplets. Low beams (called "dipped beams") have stricter control of upward light, and direct most of their light downward and either right-hand or left-hand, to provide safe forward visibility without excessive glare or backdazzle.
Headlight systems require periodic maintenance. Sealed beam headlights are modular; when the filament burns out, the entire sealed beam is replaced. Most cars made since the late 1980s use headlight lens-reflector assemblies that are considered a part of the car, and just the bulb is replaced when it fails. Manufacturers vary the means by which the bulb is accessed and replaced. headlight aim must be properly checked and adjusted frequently, for misaimed lamps are dangerous and ineffective.
Over time, the headlight lens can deteriorate. It can become pitted due to abrasion of road sand and pebbles, and can crack, admitting water into the headlight. "Plastic" (polycarbonate) lenses can become cloudy and discolored. This is due to oxidation of the painted-on lens hardcoat by ultraviolet light from the sun and the headlight bulbs. If it is minor, it can be polished out using a reputable brand of a car polish that is intended for restoring the shine to chalked paint. In more advanced stages, the deterioration extends through the actual plastic material, rendering the headlight useless and necessitating complete replacement. Sanding or aggressively polishing the lenses can buy a small amount of time, but doing so removes the protective coating from the lens, which when so stripped will deteriorate faster and more severely.
The reflector, made out of vaporized aluminum deposited in an extremely thin on a metal, glass or plastic substrate, can become oxidized or burnt and lose its specular reflective properties. This can happen if water enters the headlight, if bulbs of higher wattage than specified are used, or simply with age and use. If the reflector when viewed by itself is not mirror-perfect, the headlight should be replaced, for reflectors cannot effectively be restored.
