AndrewP-- I think a fork mounted light might really be good. It's tough to watch for potholes and cars at the same time. It's not only the amount of light your system puts out, but where that is

I think a fork mounted light, being low down and at a fine angle to the road, will spread the small beam over a longer distance in front. If it works OK I might then get a second fork mounted light for the other side. Also I have run out of mounting space on the bars.
