What is the meaning of vehicle clearance lights?

[AmaraAnn]

Vehicle clearance lights are the outermost lights located at the front and rear of a vehicle, serving as warning indicator lights to alert other vehicles. These lights are installed along the top edges of the vehicle, indicating both the height and width of the car. Safety regulations mandate that vehicles exceeding three meters in height must be equipped with clearance lights. The clearance lights are white at the front and red at the rear, designed to enhance visibility for other vehicles during nighttime driving. Other lighting systems on vehicles include: low beam and high beam headlights, commonly referred to as "headlights". The difference between high beam and low beam lies in their nighttime illumination functions - high beams project light at a higher angle with longer range, while low beams emit light at a lower angle with shorter range.
