I've always thought the best setup for pumper trucks in an urban environment (where's there's lots of intersections) is this. Having the lightbars cocked at a 45* angle really helps when approaching intersections. A large traditional single bar that's forward facing doesn't seem to accomplish that critical 45* intersection warning all that well. After all, most emergency vehicle crashes occur at intersections! While you may say the true 90* side facing lightbar provides adequate coverage; to which I reply that only does when the nose of a pumper is already IN the intersection. The 45* bar is better because it gives earlier warning as the truck is still approaching the intersection but not yet in the intersection.I also really like the lightbar mounted just below the windshield. At that height it seems to bounce the light very well off the rear view mirrors of cars in front of the truck, helping part the way better.
I'm not a fan of warning lights mounted adjacent to headlights (unless they're white headlight wigwags) because they're not that visible at night due to the headlight brightness drowning them out.
For the icing on the cake, a minibar placed traditionally & located at the very front center of the top of the cab would give even more long range warning. Of course a vintage FS Beacon Ray 175 would too, & it would look amazing imo!
