You can by the oem lights at various sites online. I did it but cannot recall where I purchased them from because I sold the Outlook. If your at all handy its not to hard to do. make sure you put the vehicle stands under it if on ramps because of the roll this vehicle has.
I bought 2 inch round led amber marker lights from a truck supply store. Drilled a 2 inch hole in the fog light block off plate slid them in from behind. They are clear when not on and are bright amber when on.
