for you night time panfisherman I bought those glow sticks that you can attach to slip bobbers. I just bought the replacement sticks and put a rubber band on the bobber befor tying the line.

They advertise a special holder for the sticks but they are expenxive and look just like a tie wrap for like $3 ea or something silly.

At any rate I fished for several hours the other night with just one stick and it  worked perfectly. I liked them much better than the heavy bobbers with the lights and batteries.

I bought the Thill bobbers when they were on sale this spring. Nice light weight bobbers, and the replacement lights are reasonably priced. I think I will go with the clip on lights like you got if something happens to these (unless I get them on sale cheap again). I don't think they are worth the retail price they ask for them. A little on the cheesy side for $5+.
