But it seems like from this quote that you think reflectivity, or passive is superior to active lighting and it's not, not even close. Instead of putting anymore effort into reflectors I would put more into lighting. All you need to add is a helmet light and bar end lights. These are great bar end lights: http://store.somafab.com/soroflbarend.html Helmet light? Just find one at an LBS that comes with a helmet mount feature which is usually just a velcro strap. I was able to take a Cateye LD600 and zip tie it to the helmet and it appears I can do the same with my Blackburn Mars4 and neither light came with a velcro strap to strap it a helmet. I like both those tail lights because both have really good side illumination especially if the Cateye is mounted vertically.
