I have just supplied this guy with some custom bags, really nice chap, he is well respected on Singletrack, posts under the name of Smudge, good friends with Trout (This will mean something to Singletrack bods)

Anyway, I said I would post a link to his site, he does a version of the DX light that some of us use and also supplies spares and battery packs for pretty much any light you want.
