I know how you feel. I had a light explode because water got into it (it was supposed to be waterproof...).
I do as you said, ziplock bags (or pieces of thick plastic) with rubber bands. It's not so much that it can't get wet as the 2 (or 3) prongs can't connect to each other via water.
I'd never seen it before, but as I said, it will ruin the bulb(s), fixtures, extension cord, but it would hopefully trip the breaker before causing a fire. Serious stuff.
