it's super easy bro. i got mine at superbrightleds.com and they were cheap and they have all colors. mine look pretty much the same as the link posted by another member here:

I was looking for old pics of the led's but since my daughter dropped my external hard drive i lost all my old pics. children are the greatest aren't they?. i also deleted my cardomain page and my youtube vid's so i really don't have any pics of my car up, lol.
Thanks. I was wondering, if I could get different colors.
