Nothing wrong with that at all. 1/2 the crap I own has duct tape, electrical tape or epoxy on it somewhere. You'll probably never need to touch that light again with that fix. The only error I've ever made when using epoxy is trying to keep something looking clean or like new or original. Screw that! If it can't be seen and it doesn't interfere with anything lay it on thick and over-do it... Heck, burry and seal it it all in so much epoxy ya can't even see it anymore! Worst case ya have to replace a part but laying it on thick with no regard to what it looks like if it can't be seen is my way of fixing things these days with epoxy.
