Just had the DRL update done to my 2014 Laramie dually at Saitta Trudeau Chrysler in Pahrump...
In the case of my truck with projector headlights, the so called "daytime running lights" turn out to be the orange front marker lights UNDER the headlights and not the actual headlights themselves! That utter disappointment aside, functionally they do work as advertised... the marker lights (a.k.a.: daytime running lights) now come on automatically when the truck is in gear and the parking brake is OFF.
So...
If you have to pay shop time to get this upgrade done (like I did), then I certainly wouldn't waste money on it.
If on the other hand you have a dealer who'll do it for free, then you might as well go for it because it certainly can't hurt anything!

Why didn't you wait till we got there next week and do it for free?
