Another two votes for Magic Shine. My rides often take me out into the wilderness and believe me its dark out there. I have one on my helmet and one on the bar. Its like taking your own street light with you. When I turn my head I can see great. I went through the battery recall but thats not a sigh of an inferior product. Remember Toyotas recall. Sometimes stuff happens, and at least they took care of it.
I give Magic Shine 5 stars.
