Fog lamp switch The fog lamps act as a supplement to the low beam headlamps under limited visibility conditions such as rain, snow, dust or fog and operate only when the low beam headlamps are on. To maximize fog lamp bulb life it is recommended that the fog lamp switch be turned off after each use prior to turning off the headlamps. Cleaning the Exterior Lamps Do not use dry paper towel, chemical solvents or abrasive cleaners to clean the lamps, as these may cause scratches or crack the lamps.
