Led notification button using USB car charger
So I was wondering if can use USB car charger to power a led notification system with light on when button pressed and light off when let go the button.
1. Button need to have ability to tolerate abuse and free from getting caught by any fabric or strings.

Avoid this button - http://www.parts-express.com/pe/showdetl.cfm?Partnumber=060-632
2. Any Led will do. Please give me options of two set of led.
3. Power supply needed.
Preferred USB car charger (charge my phone too) Similar to - http://www.amazon.com/Cigarette-Lighter-Adapter-Players-Charger/dp/B000CC6I5W
Any car charger will do if USB is too complicated.
Try avoid battery at all cost.
4. Step by step as how to wire the whole thing. Do not understand those schematic outlet unless actual pictures instruction.
I have spent few hours on Google but just couldn't put puzzle together. So want to ask the community my burning question. Then I will be up for the challenge to really build it. I do have tools to build anything. Just need schematic step by step by genius like you.
Then I will post WHY I asked this question. Thank you in advance.
