Ok, So I'm trying to make the item in the link below. The instructions assume you know how do the wiring job. But I need a little guidance.

I also want to make an LED light come on when it opens too. I have the switch mentioned in the instructions and I have soldering tools and the wire. I don't know if I need to run a wire from the MP3 player and the LED to the switch, meaning i should have multiple wires or not. I guess I have a lot of questions. I can use the MP3 player (instead of a sound recording module... unless it would be easier or wire that play button to the switch? would it?) but I didn't know if i could hook the LED light up to that board for a source of power. I don't know exactly what parts I would need, really that would be half the battle for me. Do I need a heat sink? Can I do this with just a regular LED bulb? do I need a resistor? I just need to make a light come on when the chest opens that glows a bit, I don't even need the light to go terribly far, I just need it to shine about a foot to make something in the box light up that will be translucent. Also, If I use the MP3 player, how do I attach the mini amp? I really am excited about all this but need some help since I don't know too much about this. Below are some items I was looking at that I thought I could use, but I don't know if they're too much for what I'm trying to do, or if they're even the right parts. The dome lens I wanted to use just to make my project look pretty and kind of as a buffer between the light and everything else. I will be hiding all the other electric stuff with a fake bottom. I would like to find the simplest most effective way to put this together. Opinions on parts and how to put them together would be greatly appreciated!
