Laws vary from state to state. In california, it's against the law to have any lights other than headlights, amber signal/marker lights on the front, and red tailights (no blue dots allowed) with either red or amber signal lights and red marker lights. No blue lights allowed, now strobes allowed.
Here in Texas, it's not against the law to have blue lights as long as it's obvious that they're just marker lights of some description.
Usually, the only thing you see being left on used cop cars are the pushbars, spotlights, and maybe the strobes (sans controller).
