What is the brightness of Audi headlights?

[EmiliaDella]

Brightness is generally expressed in lumens. A 75W xenon lamp with 5000LM might achieve extreme brightness, but Philips does not produce such lamps. They only offer 35W xenon lamps with 3200LM. If using xenon lamps, a low beam with 4500K (standard is 4250-4300K) is sufficient for all-weather use. The difference between headlights and low beams: The difference between headlights and low beams is that low beams can be part of the headlights, but headlights are not necessarily low beams, as headlights include both low beams and high beams. High beams focus light in a parallel, concentrated beam with high brightness, allowing illumination of distant and higher objects. In contrast, low beams emit light in a diffused pattern, covering a wider area but with a shorter range. Driving in dimly lit areas: When driving in dimly lit areas or places without streetlights, it is mandatory to turn on the low beams. In conditions of heavy fog, snow, or rain that obstruct visibility, low beams should also be used during the day. High beams should only be used on roads without lighting and when there are no oncoming vehicles, as they can severely impair the vision of other drivers and potentially cause traffic accidents.
