This taruck has factory Foglights.The Foglights only work when the headlight switch is on parklights. I installed new Fog Lights (one was out.) I checked relays and fuses. It use to work when the headlights were on low beam?

 

They SHOULD work with the headlights on low beam as well.... and turn off with the highbeams..... Is the rest of the system still stock? Do you have two or four headlights?

 

I just ordered a new Headlight switch so I will install it in a couple days when it gets here.

 

Do you have the pull out switch? Or the rotary switch? (for the headlights.)
