Its cake work. I used "Candy" Lexan body spray paint. Just make sure you remember where the needles go and to set the stop spin them counter-clockwise and you'll feel the need get tight. Oh and heres a tip, I'm not sure how other people do it but to get the needles off grab a fork and slide it underneath the needle and place your thumb on top of the needle that way it wont get away from you when you pull it off and oh dont lean the fork side to side.... you will snap the peg clean off
Supaglove sounds experienced in snapping those needles off , I removed them on the wifes xB and painted them. I didnt do anything with the LED's, which are surface mount type, so to change them out wouldn't be a big deal if you can solder. The fork is a good idea, I used something simular, oh and if you break one you CANT buy them from Toyota.
