What are the two methods of alternating high and low beams in Subject 3 lighting?
2 Answers
Directly operate the lever under the left-hand steering wheel 2-3 times without switching to low beam first. When simulating lighting that requires alternating high and low beams, it is required to operate the lever continuously three times. Usage methods: If the high beam angle is too high, it can easily dazzle oncoming vehicles and pedestrians around, affecting others' vision, which is very unsafe and impolite. Alternately turning the high beam on and off at night can replace the horn to alert pedestrians and vehicles around to avoid causing too much noise. High beams can be used when driving on highways or in rural areas without streetlights to expand the field of vision. When there is an oncoming vehicle and you need to pass each other, switch to low beam for safety and courtesy. Relevant regulations: When meeting a vehicle from the opposite direction on a road without a central divider or centerline, high beams cannot be used within 150 meters of the oncoming vehicle. High beams cannot be used when meeting non-motorized vehicles on narrow bridges or roads without a central divider or centerline. High beams cannot be used when turning at an intersection controlled by traffic signals. When driving at night without streetlights, poor lighting, or in low visibility conditions such as fog, rain, snow, or dust, high beams cannot be used when a following vehicle is driving close to the vehicle in front in the same direction.
I just passed the third driving test and realized there are nuances in operating the lights! There are two common methods for alternating between high and low beams: the lift-press method and the push-pull method. The first method involves adjusting the lights to low beam first, then quickly lifting up and pressing down like flicking a switch—similar to playing the piano. You need to do this twice consecutively to pass. Remember, the speed can't be too slow; the test system requires completing the entire action within two seconds. The second method is the push-pull style, where you push forward and then pull back. This requires a larger motion, and you need to grip the base of the lever firmly. My instructor always emphasizes keeping your palm close to the steering wheel and not letting it hover—many students fail because of incorrect hand positioning. Actually, this technique is often used in daily driving when approaching curves, as it helps alert oncoming vehicles to your presence in advance.
