This Magicshine MJ-818 Light is really very bright! supervisability and I feel much safer on my nite commute.  it very well made and fits securely to the seat post.  The light modes can be changed by rotating a silver colar round the light head.  I run it off the battery pack I got with my MJ-870 light and on flashing mode it has very little impact on the battery life.  For safety on the roads you need this!

I had used a small LED rear light runnig off 2 AA batteries until I got this and they cannot even be compared to the Magicshine MJ-818!! 85Lumens???.....its looks more like 150 Lumens; cars will not ever miss you with this on.  I wouldn't cycle on the road at night without it, in fact I am tempted to use it as a day running light, like cars are doing now.  visability and safety even during the day is massively improved.
