I have a 10 watt Nighthawk and have been mistaken for being a motorcycle... I use it for riding on the trails at night and for touring down the open road but it is too much for urban commuting in a well, and often over lit city. I have a 2 watt PB headlight which works well for night riding and it's output is great... it cost $32.00 while the Nighthawk was $100.00 some years ago.
