Yes, Underglow lighting is legal in Colorado but strictly regulated under state traffic and vehicle equipment laws. Front-facing underglow is prohibited, while side and rear amber or red underglow are permitted if not visible from the front. Compliance with Colorado Department of Transportation (CDOT) and local municipal ordinances is mandatory, with enforcement varying by jurisdiction.
Key Regulations for Underglow Lighting in Colorado
- Color Restrictions: Only amber or red underglow lighting is permitted. Blue, green, or white lights are illegal due to their association with emergency vehicles. Violations may result in citations under CRS § 42-4-226.
- Visibility Limits: Underglow must not be visible from the front of the vehicle. Side-mounted lights must be shielded to prevent forward projection, per CDOT’s 2024 vehicle equipment guidelines.
- Local Ordinances: Municipalities like Denver and Boulder may impose additional restrictions. For example, Denver’s 2026 traffic code updates prohibit underglow in commercial zones without prior approval from the Department of Public Works.
Non-compliance risks fines up to $100 per violation, with potential vehicle impoundment for repeated offenses. Always verify local regulations before installation, as enforcement varies by county.
