Never had any problems with Cateyes actually - and certainly had no problem with them failing in the wet.
I thought I’d lost my front light a few months ago until I noticed a flashing light in washing machine. I’d left the light in my shorts and thrown them in the wash, being knocked around in the washing machine had turned them on and they survived the whole wash. I’ve used them every day since.
