Is H11 a Low Beam or High Beam?

[StSawyer]

H11 is a single-filament headlight bulb, which inherently does not distinguish between high and low beams; if the bulb serves as either a high beam or low beam in an H11 configuration, it can be directly replaced when changing the bulb. Here is a partial introduction about high and low beams: 1. Both high and low beams are used to illuminate the road ahead of the vehicle. The difference between them lies in the distance they cover—one illuminates a shorter distance, while the other covers a longer distance. 2. Typically, low beams have an illumination range of about 30-40 meters with a coverage angle of approximately 160°; high beams, on the other hand, have more concentrated light with a brighter spot, allowing them to reach higher and farther distances.
