Yes, underglow lighting is legal in South Africa but subject to strict road traffic regulations enforced by the Road Traffic Management Corporation (RTMC) and provincial traffic authorities. While not explicitly banned, compliance with the National Road Traffic Act (Act 93 of 1996) and Regulations Relating to the Construction and Use of Motor Vehicles (R.1686 of 2000) is mandatory. The 2026 amendments to vehicle lighting standards further clarify permissible modifications, requiring underglow kits to meet SABS ISO 2575:2023 standards and avoid red or blue hues, which are reserved for emergency vehicles.
Key Regulations for Underglow Lighting in South Africa
- Color Restrictions: Underglow lighting must not emit red or blue light, as these colors are exclusively designated for emergency and law enforcement vehicles under Regulation 1686. White, amber, or green hues are permissible but must not impair visibility or distract other road users.
- Installation Constraints: Lights must be mounted below the vehicle’s waistline and directed downward to prevent glare. Forward-facing or high-mounted underglow is prohibited, as it violates Regulation 1686(1)(b), which mandates that all vehicle lighting must not cause undue distraction or obstruct the driver’s view.
- Compliance with SABS Standards: Underglow kits must carry the South African Bureau of Standards (SABS) mark, certifying adherence to SABS ISO 2575:2023. Non-compliant kits risk confiscation during roadside inspections, with fines up to R1,500 under the Criminal Procedure Act (Act 51 of 1977).
