What lights should be turned on after entering a tunnel?

[McAshlyn]

After entering a tunnel, the vehicle should turn on the high beam, and switch to the low beam in advance when encountering oncoming vehicles. Turning on the headlights can alert surrounding vehicles to your position, ensuring driving safety. Situations requiring the use of high beams: 1. When driving on roads with poor lighting conditions, high beams can be used alternately with low beams; 2. When unfamiliar with the road conditions or needing to read road signs or markers, high beams can be used but should be quickly switched back to low beams; 3. When overtaking at night, alternate between high and low beams to alert the vehicle ahead; 4. When passing sharp curves, slopes, arched bridges, crosswalks, or intersections without traffic signals at night, vehicles should alternately use high and low beams as a signal.
