Does the alternating high and low beam lights finally return to the low beam?

[LaHarmony]

After alternating between high and low beams, the lights will eventually return to the low beam. Alternating between high and low beams involves switching to high beam first and then back to low beam, which is required in situations such as sharp curves, slopes, overtaking (while simultaneously signaling left), arched bridges, pedestrian crossings, and intersections without traffic signals. Below is a detailed introduction about them: Low beam: The low beam is beyond its focal point, between 1 to 2 times the focal distance, emitting light in a divergent state, which can illuminate a larger area of nearby objects. High beam: The high beam is at its focal point, emitting light in parallel rays, which are more concentrated and brighter, capable of illuminating distant and high objects.
