Thanks to the Illinois General Assembly, and the Illinois Secretary of State (IL doesn't have a DMV), I am now required to prominently post these four magnetic signs on my POV. It used to be that my letter as an authorized sales rep from one of the major emergency lighting vendors was sufficient, so unless I want "to cover everything up," or the alternative, "remove all my lighting," I am faced with this decision. Signs cost me $40 for all four, so I'm not about to change them with lettering the same shade as the silver color of the car.

If the lights are not covered while the vehicle is operated upon a highway, the vehicle shall display signage indicating that the vehicle is out of service or not an emergency vehicle. The signage shall be displayed on all sides of the vehicle in letters at least 2 inches tall and one-half inch wide. A vehicle authorized to have oscillating, rotating, or flashing lights mounted for demonstration purposes may not activate the lights while the vehicle is operated upon a highway.
