The highest rank in Cub Scouting is the Arrow of Light. Earning this rank prepares a Webelos Scout to become a Boy Scout. Scouts must complete four required adventures and three elective adventures to earn the Arrow of Light rank. For each adventure a boy completes, he receives a pin to wear on the Webelos colors or on his hat.
The Arrow of Light badge is the only Cub Scout badge that can be worn on the Boy Scout uniform when a boy graduates into a troop. Adult leaders who earned the Arrow of Light rank when they were young may also show their achievement by wearing a special square knot on their adult uniform.
