Servus people, How everything in the EU and with our state are regulated exactly like motor vehicle lighting in paragraphs. There is the German STVO § 19 para. 1 StVZO for the installation of lighting and signaling devices in motor vehicles. In addition, there is the ECE regulation R48/R87. In these regulations is also mandatory in which colors the lighting devices must have. Legal text here:https://eur-lex.europa.eu/…/? The new Bmw M4 CSL comes on the market with cool “yellow” daytime running lights.https://www.bmw-m.com/…/bmw-m4-csl.html One would like to use these yellow daytime running lights to lean on the BMW gt3 racing cars.https://cdn-1.motorsport.com/…/super-gt-okayama-testing-2022–2.jpg While the evil tuner in the control his vehicle (due to yellow manipulation of the lighting device, the operating permits are extinguished) s) on the car transporter can see and run home. If you wish the Bmw m4 CSL driver with its “GT3 lighting” a pleasant further drive.. Really a crazy legislation in the country
