Lights

Right I need a bright (enough to light up street/ see where going), c. £100 rechargeable front light.
Have plenty of decent rears, but could really use a super bright for the front.

I've read through as much of the thread as I can take in...

I'd recommend trying one of these.

The plus points are that it's ridiculously cheap and ridiculously bright (to the point where if you get the angle wrong cars going to the other way will flash you because they're being dazzled). It's also easy to mount and unmount. The downsides are that with the battery pack it's quite bulky and the quality doesn't feel great, although it's worked perfectly for me so far.
