Daytime Running Lights ("DRL", also "Daylight Running Lamps") are lights on the front of roadgoing motor vehicles, automatically switched on when the vehicle is moving forward, and intended to increase the visibility of the vehicle during daylight conditions. DRL were first mandated in Scandinavian countries, where ambient light levels are generally low even during the day. Finland was the first country to require DRL in 1972. Sweden adopted the same requirement in 1977, Norway in 1986, Iceland in 1988, and Denmark in 19 ...

A light source (filament or arc) is placed at or near the focus of a reflector, which may be parabolic or of non-parabolic complex shape. Fresnel and prism optics moulded into the headlight lens then shift parts of the light laterally and vertically to provide the required light distribution pattern. The lens may use both refraction and TIR to archive the desired results. Most sealed-beam headl ...

Automotive lighting - Turn signals. Turn signals (properly "direction-indicator lamps," also "indicators," "directionals," "blinkers," or "flashers") are signal lights mounted near the left and right front and rear corners, and sometimes on the sides of vehicles, used to indicate to other drivers that the operator intends a lateral change of position (turn or lanechange). Electric turn signal lights were devised as early as 1907 (U.S. Patent 912,831), but were not widely offered by major automobile manufacturers ...

Automotive lighting - Front position lamps and rear taillamps. Nighttime standing-vehicle conspicuity to the front is provided by front position lamps (known as "parking lamps" or "parking lights" in North America, "sidelights" in UK English, and known variously in other regions as "position lamps," "standing lamps," or "city lights"). These lamps may be white (international) or amber (North America). In North America, further conspicuity is offered by side-mounted lamps and retroreflectors - amber to the front a ...

Forward illumination is provided by main- ("high") and dipped- ("low") beam headlamps, which may be augmented by fog lamps and/or driving lamps. Automotive lighting - Main-beam headlamps. Main article: Headlamp Main-beam headlamps provide a bright, general spread of light into the far distance. As such, they are only suitable for use when alone on the road, as they will dazzle other drivers. They are usually integrated with dipped-beam headlamps. Automotive lighting - Dipped-beam headlam ...
