Long ago I started to use neodymium magnets to attach bike lights.  This particular model uses a standard Energizer red rear light, a curved magnet,  in conjunction with superglue and cotton to fill the gaps.  I simply place the light where it will not slide downward with bumps and gravity and I have never had to U-turn to pick it up.

Very clever!
