On my new 2019 F150 XL there are a pair of lights on the lower bumper about 2"x4'. I can see they have bulbs and wiring but I have no idea what they are for or how to turn them on. I've tried every switch and read the manual.

 

Welcome to the site..

Front Fog lamps?

Depress the fog lamp switch, main light switch is On (any position but Off) and that the headlights are either in park lamp, or low beam. Fogs will not come on if in high beam..

 

That worked. Thank you. I guess you need to have the lights on and key on which I didn't have before. This is my 4th F150 but none of the older ones had fog lights.

 

Post up a few pics of the new rig..
