What are the two lights at the very bottom of the car headlights?

[GabrielleLynn]

The two small lights below the front headlights of a motor vehicle are fog lights, which are used for illumination in foggy or snowy weather. Fog lights are generally yellow because yellow light has strong penetration. Marker lights and clearance lights refer to the same thing, both used to indicate the width of the vehicle. They are typically the outermost lights at the front and rear of the vehicle, and the switch for marker lights is usually the first position before the headlight switch. Generally, front marker lights are located beside the headlights, slightly dimmer than the headlights, while rear marker lights are combined with brake lights and are also red, usually positioned at the outermost edge.
