Lights

Loads of options in the list on page 1 of this thread. Some of the links might be broken, but just copy-and-paste the name of the light into Google search and Robert is your mother's brother.

There was a super offer that I recommended on here recently, and many forumengers have bought it. It might suit you also, and the bonus is that because its a 2 light combo, you get a spare rear light. This can prove very handy. Only £12.95 too, so it doesn't break the bank.
