Most of those things are done automatically, and my Officers do utilize the TA, TD, and alley lights regularly. In fact, the only option that I rarely ever see them use is the rear cut. Probably smart considering the liability in it if they use it then stop on the interstate. The only price difference is buying a dual color bar as opposed to a single. It still installs the same, and the programming would have to be done regardless. And my upfitter now has a base map, don't be programming takes all of 20 min. The bar itself costs more, sure, but I could easily get away with it being the only warning light on the car.
In fact, I nearly do. Most of my cars use interior bars which also get perimeter lights, but the overhead cars get a HLF, a small dual color light in the headlight housing for corners, and a small LED in the reverse lamp housing. When all is said and done, the two cars cost within $200 of each other. Most of my Officers choose the slicktops, but I have some that prefer the brighter and more traditional overhead.
