Is Underglow Lighting Legal in New Mexico After the 2026 Law Changes?

Yes, Underglow lighting is legal in New Mexico for vehicles when compliant with state and local traffic regulations. The New Mexico Department of Transportation (NMDOT) and municipal ordinances permit underglow lighting, but only if it meets specific brightness, color, and placement standards to avoid distraction or misinterpretation of vehicle signals. Failure to adhere to these rules may result in citations under NMSA §66-3-841, which governs vehicle equipment standards.


Key Regulations for Underglow Lighting in New Mexico

  • Color Restrictions: Underglow lighting must not display red, blue, or amber colors, as these are reserved for emergency and law enforcement vehicles. Only white or amber lighting is permissible under NMSA §66-3-842.
  • Brightness and Visibility: Lights must not exceed 300 candlepower or emit a blinding effect. Excessive brightness that impairs other drivers’ vision violates NMDOT’s vehicle equipment guidelines.
  • Placement and Usage: Underglow lighting cannot extend beyond the vehicle’s lower body or interfere with brake lights, turn signals, or license plate illumination. Static or flashing modes are prohibited unless explicitly permitted by local ordinances.

Local jurisdictions, such as Albuquerque and Santa Fe, may impose additional restrictions. For instance, Albuquerque’s municipal code (Sec. 6-1-3-4) prohibits underglow lighting in residential zones during nighttime hours. Compliance with both state and municipal regulations is mandatory to avoid penalties.
