To turn on your fog lights (assuming your Mustang is equipped with them):
1. Turn on your headlights. This is usually done with a rotary switch or a stalk on the steering column.
2. Look for a smaller switch or button, often near the headlight switch, that has a symbol depicting fog lights. This symbol is usually a stylized light with a curved bottom, representing the shape of a fog light beam. Push or pull this switch to activate the fog lights.
If you can't find a separate switch and still suspect your Mustang has fog lights, check your owner's manual. It will precisely show you the location and operation of all your vehicle's exterior lighting controls. If you don't have the manual, you can usually find a PDF version online via a Ford website or a reputable automotive parts website.
