Don't do it!
In my opinion they look cheap and tacky. Mine had light blue ones when i bought the car, couldn't wait to get rid of them. I bought Cannon ones: alas no longer freely available, but do a search and you should find a Post from "Dogsbody" giving details of Cannon and they were selling off their suplus stock at reasonable prices mid to late last year. You never know they may still have some left.
Good luck,
Mike
