I have reflective tape on my bike helmets and on my wheel rims. Headlight, backup headlight, blinkies on the back of my helmet and one on my handlebar, taillight and backup taillight. Depending on conditions, I'll turn on my backup lights for the last part of my ride, which is after I exit the trail and am on the road with drivers anxious to get the heck home after work.

I'm going to get something reflective to put around the wrist of my turn signal arm (leftie), too.

Thanks goodness, only about a month to go before the days start getting LONGER.
