KATRI (Korea Automobile Testing and Research Institute) has presented KMVSS revision drafts concerning lighting systems. The purpose of the revision is to align the requirements for conformity of production for mass-produced vehicles with the relevant UN regulations. This implies that the luminous intensity requirements for the majority of lighting systems in mass-produced vehicles may have a tolerance of ±20 percent or less. However, it’s important to note that the drafts do specify the minimum luminous intensity for certain lighting systems such as stop lamps and direction indicator lamps.
