Yes, Underglow lighting is legal in Maine when installed on private vehicles, provided it complies with state and federal regulations. The Maine Bureau of Motor Vehicles (BMV) aligns with federal standards, prohibiting colors visible from the front (e.g., white, red, or amber) and requiring lights to be non-flashing. Local ordinances in municipalities like Portland or Bangor may impose additional restrictions, necessitating verification with municipal authorities.
Key Regulations for Underglow Lighting in Maine
- Color Restrictions: Underglow lights must not emit red, white, or amber hues visible from the front of the vehicle, as these mimic emergency or headlight signals under 29-A M.R.S. § 1913.
- Non-Flashing Requirement: Lights must remain steady; flashing or oscillating underglow violates federal FMVSS 108 and Maine’s vehicle equipment laws.
- Private Vehicle Exemption: Commercial vehicles and public transit are subject to stricter rules under Maine’s Department of Transportation (MaineDOT) guidelines.
Maine’s 2026 compliance updates, effective January 1, mandate annual inspections for aftermarket lighting systems in registered vehicles. The BMV now cross-references installations against the National Highway Traffic Safety Administration (NHTSA) database to flag non-compliant setups. Failure to adhere risks citations under 29-A M.R.S. § 2357, with penalties ranging from $100 to $500 for repeat offenses.
Local law enforcement in municipalities such as Augusta or Lewiston may interpret regulations differently, particularly regarding brightness thresholds. Vehicle owners should consult the BMV’s Vehicle Equipment Guide (revised June 2025) or a certified inspector before installation. Non-resident vehicles must also comply with Maine’s laws while operating within state borders.
