Wow! These are BRIGHT!! And will certainly grab your attention. We'll made, sturdy, battery compartment has rubber seal to keep out moisture. 3AAA batteries. 9 Modes. To insert batteries: Unscrew 2 visible Phillips screws on bottom. Turn them over and look carefully around the edge (see pics) and you'll notice 2 tabs to pry the back off. It's a bit firm b/c of the rubber seal, but it'll come off with a little gentle persuasion. Put in batteries, line up the tabs, & replace screws. I believe they have another item with yellow lenses. Comes with hanging tab and magnet on the back!
