That won't work Derek - you will end up with no highlight at all unless you make the area of the flashlight itself opaque. I think the original poster wants to just have an e.g. red ring for the highlight, not a filled semi-transparent red circle. I can't find anything in OD that will let you do this, so it would be a good feature to add to the next version (or, preferably, this one!).
