Sensational light and clips on to my helmet as well,
This review is from: Smart Lunar R2 Rear Light (Sports)
This lamp is sensationally bright and has some very unusual flahing modes. It supplied with a clip and also fittings - one which is big enough to go on a seat tube and one which will fit on a stay.
However I found that the clip can be used to attach it to the plastic tightening band of my helmet. It sits very comfortablly - just on the nape of my neck and produces a very visible high level rear warning light that motorists really can't fail to miss.
