My new 2016 Ram sport headlights fog up across the bottom where the turn signals are , how do i stop that only 900 miles on it

 

Moving to the correct section.


Either take it to the dealer and use your warranty or take the housing out and seal everything up with silicone.

 

Take back to dealer. They will probably re_seat the rubber grommet in the back and send you on your way the first time, but then if it continues they will replace entire assembly.
Taking it apart is a total mess and pia. I would not reccd that on a 900mi truck. You will void any future warranties on them.
