you know, the colored ring around some motorcycle tires, in the side wall. Often flashy vibrant colors.
It's called a 'Ring of Fire' and can be purchased as an accessory for any bike that has a stator (generator) that provides sufficient power to keep it lit. A mild warning. These types of lights have proven to be troublesome and some have been known to not operate correctly (eg. go out on you) However they DO look cool. lol so you have to make that choice.
