Tiny Bulb

This is the light bulb in a Mini Mag Flashlight.  This flashlight is only about six inches long, so you can see how small the bulb must be.  The bulb is only about 1/8" in diameter, and yet there is a very tiny spring-like filament inside.  The AA batteries in this flashlight leaked, and there was some white crusty stuff inside the flashlight.  Even after cleaning the crusty stuff, and with new batteries the flashlight wouldn't light up.  So I started examining the flashlight with a magnifier to see, for instance, if the filament of the bulb was blown.  That's when it occurred to me to photograph the filament so you could see how small it is.  Below is a photograph of the whole flashlight.
