When should the running lights on my 2004 2500HD be on.I have never seen them on and can't seem to get them turned on.

Mine come on when I shift out of park.

Hey thanks I hadn't thought of that but it sounds logical that they would work that way.

Yep, shift out of Park, they come on.


You can turn them off by twisting the headlight knob to the off position when the truck is running. They will stay off until next key cycle.


Nice little tip for you. http://www.dieselplace.com/forum/smileys/Big Smile.gif
