HM CSL Yellow DRL LED Headlight Module Set - F90 M5 | G30 5-SeriesOne of the special details of the new BMW M5 CS are the motorsport yellow daytime running lights. Evoking the look of GT racing cars, the BMW Laserlight headlights with yellow running lights bring a touch of the racetrack to the front of the new BMW M5 CS. Both in the welcome sequence triggered when unlocking the doors and when the low and high beam headlights are switched on, the angular daytime running lights illuminate in yellow rather than white.
