I can attest to how ACC works on my 2016 Grand Cherokee, which I assume will be the same on the JL Rubicon I've ordered (which I had to include the Advanced Safety Group specifically because I wanted ACC).
I rented a travel trailer and pulled it up into Colorado last summer. On the Million Dollar Highway between Durango and Ouray, I set the cruise to 30 mph on the slow twisty curves. On the steep downhills I was beyond impressed with the technology when I realized that the Jeep was hold hill descent speed using a combination of downshifting and brakes. In my side and rear view mirror I could see the reflection of the brake lights off the trailer when brakes were applied.
So I assume, even without towing a trailer, if a quick "collission avoidance" type of slowdown or stop was triggered, the brake would deploy and the brake light would come on. But on normal "take foot off the gas" slowdowns by the ACC, no brake light comes on because brakes are in fact not being used.
This is all speculation as to how it might apply to the JLUR w/ACC though.
