I had this idea last year, made a few and tried them this spring and it worked just fine. Buy a tube of the glow sticks from Wolf Products and in the bottom of one end is a bag of connectors to let you make a circle out of the sticks around your foam bobber. Hot Glue the connector to the bottom of a prescription pill bottle and throw the cap away. Drill a small hole in the side of the pill bottle at the open end (away from the glued on connector) and tie a 6 foot long piece of string or monofilament line to the pill bottle through the hole you just drilled. I roll the string up around my finger and push it in the bottle for storage until needed. When your ready to fish at night activate a glow stick and push it into the connector on the end of the pill bottle and tie the end of the string to some thing that is secure but do not tie it to your pole, tie it to your rod holder. Throw your bait out and leave a little loose line, slip the pill bottle with the glow stick over the tip of your pole and just watch. When you get a bite the line will tighten up and pull the pill bottle off the end of your pole letting it fall to the ground or in the boat. A lot of movement that wakes you up and easy to see. Anyone needs pictures I could take some but it's super easy to make.
