Guide To: ECE R86 - Installation of lighting and light-signalling devices for agricultural tractors

UN ECE R86, or Regulation No. 86 of the Economic Commission for Europe of the United Nations, is a regulation that specifies the requirements for the installation and performance of fog lights for power-driven vehicles and their trailers. These devices are used to improve visibility in fog or other conditions of reduced visibility.

UN ECE R86 applies to fog lights that are either stand-alone or built into other light units, such as combination or multi-function lights. The regulation specifies the size, shape, color, and photometric performance of fog lights. It also specifies the test methods that must be used to verify that fog lights meet the requirements of the regulation.

UN ECE R86 is recognized by many countries around the world. This means that fog lights that have been approved under UN ECE R86 can be used on vehicles in these countries.

Here are some of the key requirements of UN ECE R86:

Fog lights must be yellow in color. Fog lights must have a minimum photometric performance. Fog lights must be mounted at a height of at least 250 mm and not more than 1,000 mm above the road surface. Fog lights must be mounted at a distance of at least 400 mm from the side of the vehicle. UN ECE R86 is an important regulation that helps to improve the safety of vehicles on the road. By requiring fog lights to meet certain standards, the regulation helps to ensure that these devices are effective in improving visibility in fog or other conditions of reduced visibility.

Here are some additional points about UN ECE R86:

Fog lights must be marked with the UN ECE R86 approval number. Fog lights must be installed in a way that ensures that they are visible to other road users. Fog lights must be switched on automatically when the fog lights are switched on.
