Hey! I'm new to this Dodge diesel scene.I just purchased a 2006 Atlantic Blue Dodge SLT diesel.It's a beautiful truck but I have a question.
When the running lights are on and you signal left or right,are the corresponding running lights suppose to go out?
Example Left signal light,left running light.Right signal light,right running light.Dealership says thats normal.Thoughts?

 

what model truck is this on, SRW or DRW? need a little bit more info on the truck

 

It's an SLT.

 

It's normal. Without heaadlights on, the same side daytime running light (headlight) will turn off when signaling for greater visiblity of the signal light.
