Thanks everyone. I can't really show you how to do it. I can tell you what you need.
Soldering iron 15-20 Watt with fine tip
Solder
0603 size SMT L.E.D
And Skills
I don't recommend anyone to do this unless you have done this before or have done other really small soldering. It is extremely easy to break the contact on the board and never get it back.
Heres the board with the orignal l.e.ds on it. I dont have a pic with the new , but it looks the same pretty much.
