Thill Splash Brite Lighted Slip Bobber 2 Pack TSB00 | eBay
A long time ago I used to use these bobbers that used the small glow sticks, The bobbers had a swivel on the bottom and the top stem would lift off. You would put your light stick in and slide the clear top stem over it. I loved them but my local sports store quit carrying them. Have any of you ever seen or used these and are they still available ? I have one left but have lost the top. I can't remember where I put it but when I find it I'll post a picture.

I've seen that type of bobber for sale on places like eBay, but I just use the Thill balsa floats with a nub on the top. A glow stick with a 4.5mm diameter fits right over the nub. You can buy them in bulk on eBay, and they come with sleeve to mount them on the float.
Don't worry, catch crappie.
Babe Winkleman showed night fishing with this bobber.
