Abstract: A light attached to an end of a hollow handlebar of a bicycle includes a first portion (a portion exposed outside the handlebar) accommodating a light emitting unit and a battery; a second portion (an insertion portion) configured to be inserted into the hollow handlebar to fix the light to the handlebar; and an adjustment mechanism configured to adjust a maximum width of the second portion, the second portion having a space therein, the adjustment mechanism adjusting the maximum width of the second portion by using a rod-shaped member extending through the space in the second portion in an axial direction of the second portion to change an axial length of the second portion.
