The helmet has a translucent blue mohawk that is illuminated with LED lights! The lights power on and off with a button located at the back of the helmet, and can be set in steady, or flash mode! Recommended for riders 8-14 years old, but will fit most with a heads measuring 54-58 cm. Complies with the U.S. CPSC Safety Standard for Bicycle Helmets for Persons Age 5 and Older.
