OK, this is officially a trend now.
While I'm from Milwaukee, I live in the NW suburbs of Chicago now, and 3 surrounding departments have switched to the black-and-white motif.
Minneapolis making the switch too, see the Minnesota forum for that.
Same for Minnesota State Patrol, but it's a variation on colors, they snuck in a dark maroon. Looks nice.
Since I really like the design, I'm happy with this, but it is possible to make some bland designs. I like the CHP, they have a really nice one that's also very classic at the same time.
I never liked the colorful wrapping, it started to over the top.
Regarding lightbars, with the price of gas I suspect there will be a ton of low-profile LEDs for the next few years. Anyone remember the Aerodynic from FS?
