Despite being disposable, this little light is actually quite a good idea for sticking to distribution boards with its built in magnet. It's got a sealed case so I presume it's waterproof, and the switch is momentary, so it can't be left running.

The circuit relies on the internal resistance of the cells to limit the current . It still drives the LEDs hard though.
