nope, brakeless you NEED these puppies

Got the single version of these, used it on Dunwich and loved it. Seriously bright, good run times, pretty cheap (for these sorts of things) at £150 rrp. I paid much less due to a kind friend who works in the bike trade.

They come with belt clips, I got one on the front of my bag, one on the back.

i wouldn't use a knog or similar as my sole souce of being seen on the road. they are just not bright enough.

I have onew of these, ideal for throwing on if you get caught out in the dark, fit nice and easily too.

I had one of these, but it got nicked. One of the disadvantages if you forget about em :)
Also, I found that when you put it in your bag it tends to switch on very easy and when you get it out, its flat. Bad design IMO, won't buy again for that reason, everything else about it is great..

+another for these... been using one for years, not expensive, easy attachment, and nice and bright.
