Here are My PIAA lights. These are the cat's meow. I ride to work about an hour each way. Mostly before sun rise. They light up the old country ride like it's noon. I have the right side light turned slightly out to show the ditch. Great for showing me the deer and other critters. Two day's ago I had a brown bear cross in front of me on the bike. I think I would have seen him even without the lights. I've riden all my life and the first Bear sighting was on a road bike.
