What is the B2 night driving light usage tutorial?

[StRylee]

B2 night driving light usage methods: 1. Correctly turn on lights during night driving: Use low beams when following another vehicle closely in the same direction, alternately use high and low beams when navigating sharp curves, slopes, arched bridges, crosswalks, or intersections without traffic signals. 2. Properly use low beams when turning at intersections: Alternate between high and low beams when overtaking to alert the vehicle being passed, use low beams when driving on well-lit roads with streetlights. 3. Night driving light simulation test begins: Turn on vehicle lights, activate low beams, drive on unlit roads at speeds exceeding 30 km/h, switch from low beams to high beams, when there's a vehicle ahead traveling in the same direction at close range. 4. Alternate between high and low beams three consecutive times as a signal: Now driving on well-lit roads with streetlights, correctly use low beams when overtaking the vehicle ahead. 5. Now driving on unlit roads: Speed exceeds 30 km/h, correctly use high beams, when an oncoming vehicle approaches, prepare to meet, switch from high beams to low beams.
