I bought a Nite rider last season, I am not sure the model number but it is the single beam. I had probably spent $100 on flashlight type lights and cheaper lights. Just get a night rider and save yourself a lot of trouble. the best thing is you can see where you are going. It is also mounted with a rubber band and the battery with a velcro strap, I can take mine off the bike in seconds and put it back on and aim in about as eaisly.
