Guide To: ECE R37 - Filament light sources

UN ECE R37, or Regulation No. 37 of the Economic Commission for Europe of the United Nations, is a regulation that specifies the requirements for filament lamps for use in approved lamp units of power-driven vehicles and their trailers. These devices are used to provide illumination for vehicles.

UN ECE R37 applies to filament 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 performance of filament lamps. It also specifies the test methods that must be used to verify that filament lamps meet the requirements of the regulation.

UN ECE R37 is recognized by many countries around the world. This means that filament lamps that have been approved under UN ECE R37 can be used on vehicles in these countries.

Here are some of the key requirements of UN ECE R37:

Filament lamps must be of a type that is approved for use in approved lamp units. Filament lamps must be able to withstand a certain amount of vibration without deforming. Filament lamps must be able to produce a beam pattern that complies with the requirements of UN ECE Regulation No. 48. UN ECE R37 is an important regulation that helps to improve the safety of vehicles on the road. By requiring filament lamps to meet certain standards, the regulation helps to ensure that these devices are effective in providing illumination for vehicles.

Here are some additional points about UN ECE R37:

Filament lamps must be marked with the UN ECE R37 approval number. Filament lamps must be installed in a way that ensures that they are aligned correctly. Filament lamps must be replaced if they are damaged or become defective.
