I use the Vision 2 on me bars and one of cheap deal exreme torchs on me head son.
The Vision is ok on its own but as your bars aren't always facing where you want to go i find a helmet light means i can ride more techy stuff.
There are brighter lights than Hope but i reckon my Vision will last for ages, although as Led technology is moving fast there might be a good argument for selling on and upgrading while they still have a decent value?
We did a group buy from a guy in Scotland last year. Vision 2 with 2x batterys for £160 each. Think it was Gravity Sports or something like that?
