One night a few years ago my wife and I were walking on one of our multiuse gravel, little traveled trails. Off in the distance we saw these amazingly bright lights heading our way. We thought it was a car - but, lo and behold, it wa a bike with a dual light system. I was very impressed, both because they could see so very well on this somewhat winding trail, and, mostly, because I could see the bike so well. I thought - that looks pretty safe when competing with car lights and the like.

So, I just installed a dual light system, one 5 and one 10 watt light on my bars. They are really great. I mostly am using the 5 watt, but when I am going where I know there are deer and other animals on the trail (through past experience) or the trail is windy, I will turn on both - and wow, I can really see. Also, at age 62, your night vivion leaves a little to be desired.
