Usage of neon underglow lighting is governed by Illinois Vehicle Code, Chapter 12: Equipment of Vehicles, Article 2: Lights and Lamps.
Is neon underglow legal in Illinois?
Illinois law restricts vehicles from having additional lighting not specified in the Vehicle Code. Therefore it’s our conclusion that in Illinois neon underglow is illegal.
In addition the law does not allow the usage of flashing lights nor emitting red color in front of the vehicle.
Furthermore the law forbids possession of any rotating, oscillating and flashing lights capable of producing an effect which may give the appearance of an emergency vehicle. Ensure you never use any illumination which is capable of displaying blue and/or red colors, or any kind of flashing underglow. An over-eager LEO could charge you with a Class A misdemeanor simply for possession of such a system.
Legally permitted aftermarket lights in the state of Illinois only include: up to two side cowl or fender lamps, and one running board courtesy lamp on each side of your car. These lights must emit either white or amber non-glaring light.
Illinois does make exceptions for motorcycles.

Similar restrictions exist for blue and amber lights.

(a) A person, except those given exceptions in Section 12-215 or 12-609 of this Code, may not possess or be in actual physical control of oscillating, rotating, or flashing lights or other indicia of emergency vehicle authority within any portion of a motor vehicle, including but not limited to wig-wags, red and blue LEDs, sirens, mounted or affixed devices or other equipment, markings or indicia of emergency vehicle authority.
(b) A person found guilty of violating this Section is guilty of a Class A misdemeanor.
Sec. 12-218. Auxiliary accent lighting on motorcycles.
(a) A motorcycle registered in this State may be equipped with, and a person operating the motorcycle may use, standard bulb running lights or light-emitting diode (L.E.D.) pods and strips as auxiliary lighting with the intent of protecting the driver.
