Good job on the 25 LED, Knot!
Inspired by your creativity here, I bought a little LED light and put it on the bike. It sits in the bottom of the water bottle cage, face down (it's round- got it at Lowe's for $9). I put a full bottle on top of it and it stays put. It shines quite a bit of the ground below and makes me far more visible. Don't know how long it'll last with the batteries, but I bought some rechargeable AAAs, so I'm hoping it'll at least last a few days at a time.
You ladies just saved me a TON of money on a lighting system. Who knew I could buy a cheap light and get creative with it and still be seen. I LOVE alternate ways around things (read: I'm a cheapskate and love to save money to buy more bike things ).
