Great bright light,
Verified Purchase(What is this?)
This review is from: Blackburn Mars 4.0 Rear Light 2012 (Sports)
This is a great bright rear light. It's light and very bright. Also it has two AA batteries supplied, mine came with two Duracell's installed. I was looking for a bright light that definitely didn't have USB only charging. It means I can use my bank of MiHi batteries when the Duracell's run out.
