Helmet light

voltage25

I'm looking to get a light to go on my helmet. I have being looking at ultrafire and fandyfire ones but I'm not sure what to get I already have a hope vision one on the bars and would like something that would work well with it.
I want to spend £30 max as I'm just getting into night riding and was just wondering what other people are using?
Cheers
Ben
