Yes, Underglow lighting is legal in Texas under state law, but local ordinances and vehicle code restrictions apply. Texas Transportation Code § 547.303 prohibits red, blue, or amber lights visible from the front, while white or amber underglow may be permitted if not distracting or mimicking emergency vehicles. Municipalities like Austin and Dallas enforce additional rules, requiring compliance with local traffic codes to avoid citations.
Key Regulations for Underglow Lighting in Texas
- Color Restrictions: Underglow must not display red, blue, or amber hues visible from the front, per Texas Transportation Code § 547.303. White or amber underglow is permissible if not confused with emergency lighting.
- Visibility Limits: Lights must not project beyond the vehicle’s perimeter or impair the driver’s vision, as outlined in Texas Administrative Code § 17.40. Local jurisdictions may impose stricter visibility thresholds.
- Local Ordinances: Cities such as Houston and San Antonio enforce additional restrictions, including prohibitions on flashing or oscillating underglow. Violations may result in fines or mandatory modifications.
Compliance hinges on adherence to both state statutes and municipal codes. The Texas Department of Public Safety (DPS) and local law enforcement agencies monitor violations, particularly in high-traffic urban areas. For 2026, proposed amendments to § 547.303 may introduce stricter enforcement, emphasizing safety over aesthetic modifications. Consult local authorities or a traffic compliance attorney to verify current requirements.
