Yes, underglow lighting is permitted in Spain under strict conditions. The Reglamento General de Vehículos (RD 2822/1998) and Real Decreto 1428/2003 regulate auxiliary lighting, while the Dirección General de Tráfico (DGT) enforces compliance. Neon or LED underglow must not exceed 500 lumens, emit red or blue hues, or impair visibility. Non-compliance risks fines up to €200 and mandatory removal.
Key Regulations for Underglow Lighting in Spain
- Color Restrictions: Only white or amber underglow is legal; red, blue, or green lights are prohibited as they mimic emergency or police vehicles (Art. 12.5 RD 2822/1998).
- Luminosity Limits: Auxiliary lighting must not exceed 500 lumens to prevent glare or distraction (Art. 4.3 RD 1428/2003).
- Installation Constraints: Underglow must not project light upward or interfere with vehicle identification plates or reflectors. Permanent modifications require homologation (ITV certification).
Enforcement and Compliance Shifts The DGT conducts routine inspections, particularly in urban areas like Madrid and Barcelona, where non-compliant vehicles face immediate fines. A 2026 EU directive (2024/1255) may harmonize underglow standards, potentially tightening Spanish regulations further. Aftermarket kits lacking CE marking are automatically deemed illegal. Vehicles with factory-installed underglow (e.g., some BMW or Audi models) must display homologation certificates during ITV inspections.
