LED.
Such a Tiny, Yet marvellous Invention. A Promise to make the Mankind Glow (Pun Intended).
Here, I present a new Instructable using LEDs to create a versatile, Bright and universal light

These lights work on any standard 5V DC source Like USB ports or Mobile chargers. Other option is to rig up those to 4x AA cells.
In the Photo is a Selfmade Universal Charger that connects to USB port or Wall plug adapter and can charge 3 cellphones at once.

Step 1: Find Compatiable Pins

We need some Mobile charger "adapter pins" as they're called here in India. They're just 10 Rupees a piece.

Step 2: Heads Off!

We need the female sockets that come with these adapter pins. Here is where we can connect the LEDs.

Step 3: Strip and Attatch

Extend wires if you need to.. But I prefer to keep things short and sweet.

Step 4: Bring on the LEDs

I have connected the Pre-made LEDs that are wired to accept 5 volt inputs. You may use any number of LEDs , But really large numbers will get cumbersome. I have chosen 6 LEDs for each application. Cover the whole thing in tape or some neat insulation. I'd prefer sillicon over everything other than light LEDs. Make sure the thing will handle daily use.

Step 5: All Forces Combine!

You may make various versions once you get the basic idea. They're really simple and fun!

Step 6: LED There Be Light!

Plug in and Enjoy!
Bright and neat light. They're good enough for many things.
