Yes, Underglow lighting is legal in Finland but subject to strict vehicle equipment regulations enforced by Traficom. Neon or LED underglow kits must comply with the Finnish Road Traffic Act (Liikennelaki 729/2018) and UNECE Regulation 48, which mandates that external vehicle lighting must not impair visibility or mislead other road users. Aftermarket installations require type approval, and improper use risks fines up to €120 under the Penal Code (Rikoslaki 39/1889). Recent 2026 amendments to Traficom’s vehicle lighting guidelines further clarify permissible color ranges (white/yellow/amber) and prohibit blue/red hues to avoid confusion with emergency vehicles.
Key Regulations for Underglow Lighting in Finland
- Color Restrictions: Only white, yellow, or amber underglow is permitted; blue, red, or green lights are banned to prevent misidentification with emergency services.
- Installation Compliance: Aftermarket kits must undergo Traficom type approval (ECE R48) and be installed by certified professionals to ensure alignment with Finnish vehicle lighting standards.
- Operational Limits: Underglow must not exceed 500 candela per light unit and must be deactivated when the vehicle is stationary or in motion below 5 km/h to avoid distraction.
Non-compliance may result in vehicle inspection failures or administrative penalties. Traficom’s 2026 enforcement updates emphasize pre-market certification checks, particularly for LED strips exceeding 30 cm in length.
