Update on the helmet lighting. The Fiber Optic lace arrived from Hong Kong although very cool in theory does not throw enough ambient light to be visible more than 4' away. The tube length is 3'. Brightest where closest to the LEDS (where you need it the least).

2ManyBikes sent a runner's arm band with 4 LEDs and reflectant. Had it out in daytime traffic but couldn't tell it it made much difference. Will have to have someone take my picture at various distances for day and night.
