Marwi NightPro Extreme circa 2010. EXTREMELY bright and wide path blazed at night. Battery pack is heavy comparatively, but it was like having a train headlight on my helmet. Raced in it and could reliably see 8-10 feet ahead and all of the width of the trail with obstacles. In my opinion, nothing like this has replaced it. It was only used for a couple of seasons in which I had a few night events. *TESTED*
