In reply to ChrisJD:
Nice - anything that helps visibility is a good thing.
Could certainly have done with some of that on the Ninja biker I saw on the road at the weekend - black bike, black clothes, black bag, black helmet, no lights.
I've got these on my commuter bike at the moment: They need taping on if you've got thin spokes, or they slide and rattle at low speed, but you can get a pack for under £5 in Halfords and occasionally Aldi do them in their bike bits.
