I fish at night quite a bit, and that makes watching your rods a bit difficult especially if you don't use a lantern because of bugs. I have tried the lit bobbers but I like fishing deep and they drift into my other lines. I found some tiny glow sticks that are designed to clip on the end of rods but the initial cost is about $5 for several little plastic clips and one tiny glow stick.

I was cutting through the birthday card section of Wal-Mart and in the kids party favor area they have glow sticks and glow bracelets for 97 cents a 5 pack. They even have larger packs of 40, 65 and 100. The 100 pack is only $10.

I clipped them on my rods 2/3 of the way up and they don't mess with my casting.

nice tip!

Might want to check dollar tree for those as well, i have seen them in there before.
Not sure of the quantity for the $ tho

I am all for creative engineering, especially when adds to the fun. Good tip
