First time using my generator light set. Its a real cheap set I picked up for like $12 at Target. It worked fine. The light gets pretty dim when I'm going up this one hill, but the suns coming up by that time and I can see just fine. I imagine later on I'll either use the Cateye to supplement the generator light on the hill or I'll just have to get stronger so I can go uphill faster. Either way, it works.
