Grynx.com: "Do It Yourself" TicTac flashlight
You may not need to make your own flashlight at present but maybe at some point in the future the probability of you having to put together a light source may become a critical reality. What would you do then? Put together a flashlight from whatever nicknacks are available.

Yes the batteries fitted perfect - I soldered them in series and used a small micro switch from an old circuit-board together with an ultra bright white LED (25.000 mcd - 3,8 volt and 20 mA - 35 degrees) and a serial resistor of 27 ohm (to make it 3,8 Volt).'
