Whilst not an ideal solution, until you get the bit you're after, electrical tape and a pit of an old tube can combine to form an excellent gripping surface for such items. Also I have found running the light/bracket upside down - so under the bars as opposed to over, goes a long way to curing the light falling forward problem.
