Both high beams and low beams are used to illuminate the road ahead of the vehicle. The difference between high beams and low beams lies in the distance they illuminate—one shines closer, while the other shines farther. Typically, low beams have an illumination distance of about 30-40 meters and a coverage range of approximately 160 degrees. High beams, on the other hand, have more concentrated light with a brighter spot, allowing them to reach higher and farther distances. Below is relevant information: Switching between high and low beams: While driving, the driver should immediately switch from high beams to low beams under the following circumstances: 1) when an oncoming vehicle is approaching; 2) when the distance to the vehicle ahead in the same direction is relatively close; 3) when the road is already sufficiently illuminated; and 4) when entering a busy street. Additional information: The left symbol with a straight line represents the high beam indicator, while the right symbol with downward-slanting lines represents the low beam indicator. (Some car models may not display an indicator when low beams are activated.) The switch for toggling between high and low beams is usually located on the left side of the steering wheel. As shown in the illustration, when the switch is turned to the low beam position, pulling the lever inward will flash the high beams once, while pushing it outward will keep the high beams on continuously.
