The Flashball, also called "patoraito" (パトライト), is without a doubt Bosozokus and Kyusha lovers' favorite accessory! The Flashball was originally designed as a warning light when you had your car stopped on the side of the road because of mechanical issues. Only the purple type was then allowed as the red color was associated to Police cars. Bosozokus put them on the side of their bikes or on top of car backboards and light it up at night.
