No, they aren't triggered by the door handle itself, but I'd bet that when you close your door, it is barely shutting off the lights!! Try sitting in the truck with the door closed, and then try just pushing on the door (not the handle to open the door) and see if the lights come on! I'm not exactly sure but I think the sensor is integrated into the actual locking mechanism on the door internally! But yes, that wouldn't be good if they open whenever you use the door handle, I'd be getting that fixed or at least doing the dome over ride button on the headlight switch, that should keep the lights from coming on with the handle until you get it fixed!
