Fog lights can be used when
The front fog lights can operate when the parking lights are illuminated or when the Toyota Tacoma headlights are on in low beam. If these lighting conditions are not met, switching the fog light control to the ON position will not activate the fog lights.
During rain, fog, or similarly reduced-visibility conditions, use the Toyota Tacoma fog lights together with the appropriate exterior lighting rather than relying on them as a substitute for the low beam headlights.
