Yes, Underglow lighting is legal in Illinois when installed on vehicles, provided it complies with state vehicle equipment regulations and local ordinances. The Illinois Vehicle Code permits non-flashing, non-glaring lights that do not exceed 300 candlepower, while prohibiting red or blue lights reserved for emergency vehicles. Local municipalities, including Chicago and Springfield, may impose additional restrictions, such as prohibiting underglow in certain zones or during daylight hours.
Key Regulations for Underglow Lighting in Illinois
- Color Restrictions: Underglow lights must not display red, blue, or any other color reserved for emergency, school, or service vehicles. Amber or white lights are typically permitted.
- Visibility and Placement: Lights must not be visible from the front of the vehicle or exceed 300 candlepower. Mounting below the bumper is generally allowed, but side-mounted lights may face local scrutiny.
- Operational Limits: Underglow lighting must remain non-flashing and non-glaring. Illinois law aligns with federal standards under FMVSS 108, prohibiting lights that impair visibility or distract other drivers.
Local enforcement varies; for example, Chicago’s municipal code may require underglow to be covered or deactivated in residential areas. Violations can result in fines or mandatory removal, as per 625 ILCS 5/12-212. For 2026 compliance, monitor updates from the Illinois State Police and the Illinois Department of Transportation, which periodically revise vehicle equipment guidelines.
