No, underglow lighting is prohibited in Thailand under the Road Traffic Act B.E. 2522 (1979) and Ministry of Interior Announcement No. 32 (2016), which classify such modifications as unauthorized vehicle alterations. The Royal Thai Police and Department of Land Transport enforce these restrictions, citing safety risks and potential distraction to other drivers. Recent 2026 compliance directives further tighten enforcement, requiring pre-approval for all vehicle modifications.
Key Regulations for Underglow Lighting in Thailand
- Prohibition on Color and Placement: Underglow lights emitting red, blue, or flashing colors are banned, as they conflict with emergency vehicle signals. White or amber lights are permitted only if non-distracting and mounted below the bumper line.
- Static Installation Requirements: Any approved lighting must remain stationary; dynamic or animated effects violate DLT Technical Standard 56-2544 for vehicle modifications. Unauthorized installations risk fines up to 5,000 THB or vehicle confiscation.
- Inspection and Certification: Vehicles with underglow lighting must pass annual inspections by the DLT, which verifies compliance with Announcement No. 32. Failure to disclose modifications during registration renewal may result in penalties or mandatory removal.
