LED Mod Your Gameboy Color

Step 4 Diffuse the LEDs

Now it's time to diffuse the LEDs. There are lots of guides on how to diffuse LEDs, so I won't go into great detail here. But you basically just rub the LED on the sandpaper so that the LED looks "rougher". Make sure you get the entire LED, or you will have bright spots.
Why diffuse it? Diffusing the LED makes it not as bright, but makes the light more spread out, which is ideal for this project. Photos three and four show you the difference between a diffused LED and a stock one.
