I have three sons and have given them 9 LED 3XAAA lights, 1W Camo Energizer 2XAA lights ($5 on sale at WalMart), and Husky LED 3XAAA headlights. I picked up a package of two headlights (two-mode white + red), three 6 LED 3XAAA lights and 15 AAA batteries at Home Depot for $14.99 just the other day. They seem to favor the camo 2XAA lights and the headlights. BTW, none is too bright, and I don't worry about eye injury.
