Daytime running lights (DRL) are designed to make a vehicle more visible to other road users whilst driving during the day.
Unlike low beam headlights and high beam headlights, daytime running lights are not primarily intended to illuminate the road. Their main purpose is to improve the visibility of the vehicle.
The device carrier (RAM Mount) is the actual holder of a RAM Mount system. It holds, for example, a laptop, mobile phone or monitor, but also clipboards, holders for protective equipment or simply drinks. …
The decibel (unit symbol dB) is a derived quasi-unit for loudness. It is not a true unit, but rather an indication that the value given is the decadic logarithm of a ratio. Generally speaking, a 10 dB increase in sound pressure is perceived by a person as approximately twice as loud. …
Die Deutsche Gesetzliche Unfallversicherung (DGUV) unterteilt Fahrzeuge nicht nach EU‑Klassen, sondern nach DGUV‑Fahrzeugkategorien (oder Prüfkategorien), um die wiederkehrende Prüfung nach § 57 DGUV Vorschrift 70/71 „Fahrzeuge“ organisatorisch zu vereinfachen. Grundlage ist der DGUV Grundsatz 314‑003 „Prüfung von Fahrzeugen auf Betriebssicherheit“. …
Die casting is a manufacturing process in which molten metal (often aluminium, zinc or magnesium alloys) is forced under high pressure into a mould (casting mould). The metal solidifies rapidly and is then removed.
Diffusion discs are used in various forms of lights for modelling the desired beam pattern. They are transparent and often form the actual front side of the light. They can be combined with lenses and/or parabolic reflectors.
DOT approval is an official marking from the United States that shows that a vehicle part or technical component meets the requirements of the U.S. Department of Transportation (DOT). It is mandatory for legal use in road traffic, especially in the USA. …
Products that have passed a test according to the rules of the Department of Transportation (DOT) can be marked with the DOT test mark. In contrast to the ECE test mark, no conclusions can be drawn from this marking as to the type of test.
In a RAM Mount system, a double socket arm sits between the base and the device carrier. This allows flexible adjustment of the mounting angle and distance.
A double socket arm has spherical recesses on both sides that can accommodate the balls of the …
In the context of a work light, dual beam refers to the combination of two different light distributions or light functions within a single headlamp.
With conventional headlights, you can often choose between low beam and high beam. As soon as the high beam is switched on, the low beam is switched off. In headlights with dual burn, however, the low beam remains on even when the high beam is activated. The result is significantly better illumination of the road.
With this form of cornering lighting, the beam of a headlight is shifted towards the inside of the bend when driving around. This shift is achieved either by mechanically adjusting the headlight optics, i.e. the light source or the reflector, or, in the case of modern LED headlights, by selectively …
