Ever looked at your keyboard in dark?There are a lot of keyboard illuminating solutions on the market but their aren’t cheap for such simple thing and some of them could damage yours keyboard.With two LEDs, two small 3V batteries and two clips you can easy make keyboard backlight by yourself.
Here is the clip that you can buy in almost any shop that will do the work. You also will need a small twisted pair cords, a solderer, a wire cutter, a piece of thin cardboard and an electrical tape to connect the whole thing.

You need to create a wrapper for the battery from the cardboard and the electrical tape. The wrapper should allow to easily remove the battery in order to turn on and off the light.

That wrapper will also hold two connected to the battery wires. You also need to wrap this battery construction to the clip.

The next step is to solder these two wires to the LED.

Now you can test your work
