I'm involved with EMS and have opted for a reflector assisted dash light which fits great on the huge dash that we have in our vehicles. It gets the light at eye level where the drivers ahead of you can see it and, believe it or not, they actually move for you. I've been in the "business" for over 15 years and have found the dash mounts to be the most effective. You can get some great additional effects from strobes mounted in your headlights also. Then you won't have the holes in your roof or that big clunky look that comes with putting bar lights on your personal vehicle. Leave them on the fire truck, where they're supposed to be.
Be safe in what you do.
