Princeton Tec Amp 1L Mini Flashlight (Neon Yellow)

The tiny, 2-ounce, 328' depth-rated Amp 1L Mini Flashlight from Princeton Tec features two modes of use, a handy hanging loop, and a bottle opener. It's a 100-lumen flashlight, but it comes with a diffuser cone that converts it to an area light or marker light. On-off switching is accomplished by twisting the light's head, and runtime on a fresh pair of AAA batteries is 72 hours.
