Is the alternating light in Subject Three switched twice or three times?

[StHolden]

In Subject Three, the alternating between high and low beams requires toggling the lever twice. Method for alternating high and low beams: Locate the light control lever on the left side of the steering wheel, first turn on the low beam, then pull the light control lever towards yourself once. The high beam will temporarily turn on, and upon releasing, the lever will spring back, automatically turning off the high beam while keeping the low beam on. One complete alternation between high and low beams is thus achieved. Usage scenarios for high and low beams: During the Subject Three test, upon hearing prompts such as 'approaching a sharp curve,' 'approaching a slope,' 'approaching a bridge,' 'approaching a crosswalk,' or 'approaching an intersection without traffic signals,' you must alternate between high and low beams no less than twice. When prompted to 'overtake, please use the correct lights,' first activate the left turn signal, then alternate between high and low beams no less than twice, followed by activating the right turn signal.
