Not the greatest pictures but you get the idea. I think these are replicas of the JDM visors. Picked them up on ebay, offered the seller $15 and he went for it, and it looks like he has a bunch more in stock.: Toyota Prius 2004-07 2008 2009 Rain Guard Window Visor: eBay Motors (item 110547270998 end time Jun-28-10 12:14:16 PDT) They are out channel, install with 3m tape.
Haha. Illest! You gotta have a fatlace one too. Nice man. I like the Weathertech ones that snap on (I don't like the tape).
