Yes, underglow lighting is permitted in Arizona with strict limitations enforced by state and municipal regulations.
Underglow lighting is legal in Arizona when compliant with Arizona Revised Statutes §28-913.1 and local ordinances, prohibiting colors visible from the front or sides of a vehicle. The Arizona Department of Transportation (ADOT) enforces these rules, aligning with federal standards under 49 CFR §571.108. Recent 2026 compliance shifts emphasize stricter enforcement for aftermarket installations, particularly in urban areas like Phoenix and Tucson.
Key Regulations for Underglow Lighting in Arizona
- Color Restrictions: Underglow lighting must not display red or amber hues visible from the front or sides of the vehicle, as these mimic emergency signals.
- Static Operation: Flashing, rotating, or oscillating underglow lights are prohibited under ARS §28-913.1, classifying them as unauthorized emergency lighting.
- Local Ordinances: Municipalities such as Phoenix and Tucson impose additional restrictions, including prohibitions on blue underglow in certain zones to prevent confusion with law enforcement vehicles.
Violations may result in citations under ARS §28-913.1, with fines up to $250 for non-compliance. ADOT’s 2026 enforcement updates prioritize vehicles with aftermarket underglow in high-traffic corridors. Always verify local regulations before installation to ensure adherence to both state and municipal laws.
