canklecat is right that a light in your wheel is a huge attention grabber. I've been complimented on mine. But I can't seem to keep it supplied with a fresh button cell battery. I can ride it in the rear wheel, but in the front, it distracts me too much.

michaelm101, reflective stuff is not nearly as effective as something that emits light. You're not guaranteed light will hit you at the right angle.
I make these fork mount for my bikes. I usually use PVC, but sometimes I use copper pipe. Miter the inner end to match the curve of the fork. Cut a couple of slits to let the hose clamp through.
