there were nothing blocking that little ball my light knob is off but every time i turn on the truck all of my exterior lights comes on. the truck came with daytime running lights but i don't see anything on the dash that allow me to turn off any feature like that.also it's not the running lights it's all of them.I would think you have a problem with the sensor on the dash. It looks like a little ball in the center of the dash close to the windshield. You may have some papers or other obstruction blocking the sunlight on it. If not, consider turning the light knob down after the truck is on. That turns the auto light feature off. Your interior dash lights will be dim but that can be rectified by turning up the intensity next to the headlight knob.
Let me know if it helps.
