So I waited for my wife to get home tonight before I went out on the bike. It was light when I left and dark when I got back.
Wow, that was super cool! Of course it wasn't on the road but down on my bike trail along the river. I went to a different spot which is only about 2.5 miles, but I left the trail when it ended and rode a dirt road that continues along the river. I rode about another 2 miles before I turned around. By that time it was dark. It is quite eerie and super cool being basically in the middle of the woods with a hill and woods to one side and the river to the other. Saw some folks coming back from fishing on the river cruising their boats down the river with their lights.
I only have 2 small multi-LED flashlights mounted to the bars, I think they are only 38 lumens each. Not very bright, but they were just for riding through the tunnels. Now with the dark coming early soon, I'll probably be out more often in the dark, definitely want to be out more often in the dark because it was so cool and need more light. The dual 38 lumen was fine, it would just be nice to have more, though I definitely would ride on the road this way.
My wife works at Lowes, thus I get 10% discount and they have an AAA 200 lumen flashlight for $9 that I think is similar size since it is still 3 AAA batteries. I am going to grab a pair of these to toss on the bike. I like the flashlight idea because they can serve dual purpose and be used at work which I am using a flashlight all the time or at home when I need a flashlight.
The only other thing that would be useful is a helmet mounted light. Hey, I want to be able to see that bear jumping out off the hill before it begins to eat me, LOL. I'll just let you guys worry about the cars out there on the road being able to see you, they don't jump out of the dark hillside and try to eat you .
