Where is the fog light switch on the Ford Focus?

[DelCharles]

The fog light switch on the Ford Focus is located on the knob below the left side of the steering wheel. Function of fog lights: When driving under adverse weather conditions such as fog, snow, and heavy rain, or in smoke-filled environments, front fog lights must be used to illuminate the road ahead and ensure driving safety. In recent years, in terms of styling design, fog lights are often installed on the front bumper. Principle of fog lights: The filament of the light source is designed at the focal point of the reflector's parabolic surface. After being reflected by the reflector, it forms a beam parallel to the optical axis. The diffuser lens spreads and refracts the beam to form a wider horizontal beam, ensuring that the light pattern and illumination meet regulatory requirements.
