In today’s globalized automotive industry, having uniform standards for vehicle safety, environmental impact, and performance is essential. The United Nations Economic Commission for Europe (UNECE) has established a set of regulations to address this need, helping to standardize vehicle construction and ensure safety across different regions. These regulations, known as UNECE Regulations, cover a wide range of vehicle components, systems, and safety features, impacting manufacturers, suppliers, and trade customers worldwide.
UN ECE Regulation No. 3 sets the standards for retro-reflecting devices used on motor vehicles and trailers, ensuring enhanced visibility in low-light conditions. These devices reflect light back to its source, helping prevent accidents, especially at night. ECE R3 outlines the approval, performance, and installation requirements for retro-reflectors, now incorporated into ECE R148 for unified light-signalling regulations.

ECE Regulation 4 applies to number plate lighting for power-driven vehicles and their trailers, whether it is for a stand-alone number plate light, or as part of a multi-function light.

UN ECE Regulation No. 5 establishes the uniform provisions concerning the approval of sealed-beam headlamps for power-driven vehicles. These headlamps are designed to emit a European asymmetrical passing beam, a driving beam, or both. Sealed-beam units (SB units) are integral lighting components that are permanently sealed during manufacture and cannot be dismantled without rendering them unusable.
Directional indicator lamps and side repeaters are covered by ECE Regulation 6. This applies whether an individual lamp, part of a headlamp or multi-functional lamp (such as rear cluster light).

The UN ECE R7, or Regulation No. 7 applies to front and rear position lighting (side lights), stop (brake) lights and end-outline marker lamps for motor vehicles (excluding motorcycles) and their trailers, whether it is for a stand-alone lamp, or as part of a multi-function light. For side marker lights, see the certification guide on ECE Regulation 91.

UN ECE Regulation No. 8 provides uniform provisions for the approval of motor vehicle headlamps that emit an asymmetrical passing beam, a driving beam, or both, and that are equipped with halogen filament
Complete vehicles or electronic sub-assemblies, such as warning beacons, alarm systems and high-mounted brake lights must be tested to conform with ECE Regulation 10, in addition to other regulations covering the particular item’s use.

UN ECE Regulation No. 19 establishes uniform provisions concerning the approval of front fog lamps for motor vehicles. These lamps are critical for improving visibility during fog, heavy rain, or snowfall, where standard headlights might not be sufficient. The regulation outlines the design, performance, and safety requirements that front fog lamps must meet to ensure both the driver’s and other road users' safety.
This regulation applies to reversing lamps and other special lamps designed to aid with vehicle manoeuvring. For the purposes of regulation, a reversing lamp is classed as a light ‘designed to illuminate the road to the rear of the vehicle and to warn other road users that the vehicle is reversing or is about to reverse’.
