Hello, I'm just wondering "because I'm new to this." How do you know which resistor and led to get rather it be a 5mm or what? And can you put more then 1 led in the mouse?

You might want to read this:

When you understand how those basics work you'll understand what you need to know to calculate those right resistors or how many leds you can add to your mouse etc. I could give these numbers to your right now but I think it's best if you understand those basics yourself too. Hope you think the same. :)

You should get a bright LED. The light is measured in mcd (millicandela) A good LED lies around 2000-3000mcd or even higher! The most LEDs are 5mm thick, so you should look for those. You can put around 10 LEDs in a mouse. You can put more, but then you must be careful not to exceed 400mA. Read the "basic elctricity" on this site and you should be on your way to become a modder :)

Edit: ohh crap, I was just writing this when japala answered :wink:

Hmm I think I would do that. Just another question. How bout exceeding 5 volts. Because I found a 5mm blue led that uses 5 volts and my mouse has 5 volts. Is that a problem or would everything work good. Would I still need a resistor?

Because you don't have any "over voltage" compared what the led needs you then don't need a resistor. You only need a resistor when you have some volts to be sinked somewhere. If you have 4 volt led you need to loose 1 volt somewhere; use resistor. :)
