I just ordered a "Nob" computer mount. Peter White has them on his web site with pictures of them used as fork mounts for dynamo lights. Their on ebay but there seem to have been 3 or 4 different brand name versions. I'm useing the "Nob" to mount a battery light to one of the bull horns of a Velo Orange Crazy bar, for the the same reason of clearing the handle bar bag.
