Lumica II Fishing Lights (Blue, White) Set of 2 I've used these for about a year, and their fish-attracting power is amazing. White is good for Seigo (young sea bass). Blue worked well for horse mackerel and mackerel. Only one of the included strings is present. The rotary switch on the white one is getting weak, but both lights have no LEDs that are out, and they illuminate normally. Batteries will be removed before shipping.
