The application of LED light to the existing air hole enables a display of dimensions on the simple bumper. And luxurious look is added to the outlook by anodizing chrome. It uses OSRAM's highest brightness LED, and is manufactured to maintain brightness even after long period of use by minimizing mechanical fatigue accumulation.
