DIY led moon lights

[LEROY]

Hey I was reading in a post that someone wired dollar store led's to a plug and I was just wondering if anyone could walk me through how to do this so I don't start a fire or anything. A diagram and parts list would help tremendously. This is a call to all you electrician diyers.
-Thanks, Steve.
