Review on Blackburn Click USB Front Or Rear Light by Jason Spainhour

Pretty light and easy to use. this way and can be very easily lost - turning off the light while holding the front is a bit fiddly and doesn't always work right away - the rubber pad protecting the USB port doesn't fit the socket that well This means that water and sand can get into the harbor if you are not careful. While the light effectively gets you seen from the side as intended, it also means there's a lot of glare shining into your eyes, which impairs night vision.
