I know it might be crazy to some, but I got promoted at the fire department in January and my ST is my daily driver, so I added lights and a siren to it for responding to EMS and fire calls. I routed all the wiring to a board I installed next to the spare to keep it nice and organized. If I could get away without the light on the roof I would, but unfortunately it's a requirement here in PA at the moment.
