Guide To: ECE R23 - Reverse Lamps

UN ECE R23, or Regulation No. 23 of the Economic Commission for Europe of the United Nations, is a regulation that specifies the requirements for reversing lamps for power-driven vehicles and their trailers. These devices are used to improve visibility when the vehicle is reversing.

UN ECE R23 applies to reversing lamps 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 reversing lamps. It also specifies the test methods that must be used to verify that reversing lamps meet the requirements of the regulation.

UN ECE R23 is recognized by many countries around the world. This means that reversing lamps that have been approved under UN ECE R23 can be used on vehicles in these countries.

Here are some of the key requirements of UN ECE R23:

Reversing lamps must be white in color. Reversing lamps must have a minimum size and photometric performance. Reversing lamps must be mounted at a height of at least 400 mm and not more than 1,200 mm above the road surface. Reversing lamps must be mounted at a distance of at least 400 mm from the side of the vehicle. UN ECE R23 is an important regulation that helps to improve the safety of vehicles on the road. By requiring reversing lamps to meet certain standards, the regulation helps to ensure that these devices are effective in improving visibility when the vehicle is reversing.
