What Lights Should Be Turned On Before Entering a Highway Tunnel?

[VonNicole]

Before entering a highway tunnel, you should turn on the low beam headlights. Here is a detailed introduction about car lights: 1. Headlights: The main purpose of headlights is to illuminate the road and objects in front of the vehicle to ensure driving safety. The high beam and low beam can be alternated as a signal for overtaking at night. Headlights are installed on both sides of the front of the car, with 2 or 4 per vehicle. The bulb power is 45-60W for high beam and 25-55W for low beam. 2. Fog lights: Fog lights are installed near the headlights or slightly lower than the headlights. In conditions of low visibility such as fog, snow, heavy rain, or dust, fog lights are used to illuminate the road and provide signals to oncoming vehicles. The light is mostly yellow. Yellow light has a longer wavelength and good fog-penetrating performance. The bulb power is generally 35W.
