I have pretty poor night vision, especially when there is ambient light such as car headlights. Since I have a recumbent trike, I'm right at eye level for headlights, so that only makes the situation worse.
So I have a Supernova E3 Pro Dyno light that I got last year. It works fine on roads in familiar with and have little debris and traffic (headlights).
However, on a road ride the other night, I discovered I had a hard time seeing any roadside debris, so I found myself going very slowly. I had a small helmet light but it wasn't enough.
I really want a dyno light as I have aspirations to do all night rides (8-10 hours of darkness, depending on the time of year), but maybe that's not the right solution for my problem? Maybe I need more batteries and a high powered light?
Basically, I need something that's at least as bright as the low beam on a car, I think.
