Super Formula Lights

Super Formula Lights (スーパーフォーミュラライツ) is a national formula racing championship that takes place in Japan. It is a junior-level feeder formula that uses the same single seater chassis as the pan-European Euroformula Open Championship. The series will be the first with the new branding as a feeder series for the Super Formula championship. The nomenclature is similar to that of IndyCar, whose support series formerly used the "Lights" moniker as well.

Origins
The Super Formula Lights championship started in 1979 as a Formula 3-based series originally known as the Japanese Formula 3 Championship. Because of changes with FIA nomenclature ("Formula Regional" is now used for all regional F3-based series to prevent confusion with the FIA Formula 3 Championship), and the change from Formula Regional standards used in such series (such as the Formula Regional European Championship and Formula Regional Americas Championship; in Japan, K2 Planet acquired the rights to run a Formula Regional championship in Japan, the Formula Regional Japanese Championship from the FIA) to sharing a single specification rule set with the Euroformula Open Championship, similar to Germany's Deutsche Tourenwagen Masters and Japan's Super GT sharing a single Class 1 formula touring car, on 17 August 2019 the series promoters surrendered the rights to the Formula Regional championship in Japan and rebranded the series to Super Formula Lights.

Equipment
The Series has similar rules to Euroformula Open Championship, which forced the name change in 2020.
