They should come on automatically when the vehicle is in operation. If they're not, you might have an electrical problem. If your vehicle is a U.S. vehicle and you want daytime running lights, you must purchase a daytime running lights (drl) module for about $50. and place it in the fuse area off the driver's side dash. Remove the hi beam module and then find someone with a Jeep/Chrysler computer that can flash your computer board and change the country code to Canada and voila, you will have daytime running lights.
