What lights to use on highways at night?

[OLily]

On highways at night, the width indicator lights must be turned on first. At the same time, in order to see the road ahead clearly during night driving, the headlights must be turned on. When traffic is sparse and the distance from the vehicle in front is large, use the high beams. When traffic converges and the distance from the vehicle in front shortens, switch to low beams. When changing lanes on the highway at night, always use the turn signals and observe the conditions for changing lanes before doing so, to prevent vehicles behind or in nearby lanes from reacting in time. When the vehicle breaks down and cannot move or is parked on the emergency lane, the hazard warning lights must be turned on, especially when visibility is low at night. It is recommended to park the vehicle under a streetlight so that the light fully illuminates the vehicle to alert oncoming traffic from behind.
