What does ECE R37 LEDr mean?
ECE R37 LEDr covers LED replacement light-source categories tracked under the UNECE regulatory framework. This site follows whether each category is approved, under review, or still waiting for technical work.
H11 LEDr status
H11 LEDr has been in force since November 2024. A street-legal H11 LED retrofit still depends on the approved product, the lamp application, and the rules in the country where the vehicle is used.
