What Lights Should Be Turned On in Foggy Weather?

[SanAllison]

In foggy weather, cars should turn on fog lights to alert following vehicles and prevent accidents. On motor vehicles, front fog lights are yellow while rear fog lights are red. Due to their high brightness and ability to avoid diffuse reflection caused by fog, proper use of fog lights can effectively prevent accidents. If a vehicle is not equipped with fog lights, the small lights and running lights should be turned on even during the day. The purpose of fog lights is to make the vehicle visible to others in conditions of poor visibility caused by fog or rain, hence fog light sources have strong penetration. Fog light switches generally have three positions: position 0 turns them off, the first position controls the front fog lights, and the second position controls the rear fog lights. When the first position is engaged, the front fog lights work; when both positions are engaged, both front and rear fog lights operate together.
