What lights should be turned on when a car enters a tunnel?

[LeMax]

When a car enters a tunnel, the headlights (low beams) should be turned on. At this time, the front low beams and width indicator lights will illuminate, and the rear brake lights will also light up. Since the lighting inside the tunnel is relatively dim, turning on the headlights can alert drivers of vehicles in front and behind to the position of your car, ensuring driving safety. When entering a tunnel, the car should slow down because the bright and glaring light outside the tunnel during the day contrasts sharply with the relatively weak light inside the tunnel. This transition can cause a brief period of eye adjustment for the driver, during which their judgment of road conditions may be impaired. Turning on the car lights not only helps in observing the road conditions but also serves to alert other vehicles.
