• With the dimmable circuit, you can adjust the brightness of the position and brake, as well as stepless adjustment to your preference • Uses ultra-bright 3-chip hat-type LEDs, so it is quite bright for the number of LEDs • The current limit uses CRD (constant current diode) or CCR (constant current regulator). Unlike resistors, it provides a stable current to the LED regardless of the voltage change, and it generates less heat • Comes with a switch to get it back to original. (Because it has been processed with genuine reflectors, it plays the role of a regular reflector when it is not glow.) • Reflector function, size, fixing method, and wearing feel are all OE equivalent and waterproof perfectly. We have a 1 year warranty because we are confident in processing
