Also refers to rolling up to a call-in progress with all of your vehicle lights turned off. Many agencies use "black-out switches" that will deactivate your brake lights. You can turn off all of your lights as you approach, and also kill your brake lights, so the light doesn't announce your arrival. Some officers cruise alleys "blacked out" looking for taggers, burglars, hookers, etc. Sometimes referred to as stealth mode.
