The Rozemeijer Fluo Green Lights are designed to be placed on the Pike Floats with Light and/or the Dart Floats with Light. These floats are supplied with an orange cap as standard; however, it can sometimes be convenient to switch to a different color. Consider situations where you are fishing with multiple floats, or with multiple fishing buddies, and you want to be sure that it is your float that goes under and not your buddy's. 2 pieces per pack.
