I saw a white 4th gen yesterday that had a pair of really cool looking "fish-eye" mirrors mounted on the original mirrors. These weren't the typical 99¢ stick-ons. They were in their own housing and looked completely stock. They looked like the parking mirrors you see on the fenders of Hilux Surfs. Does anyone know if this is a dealer option or if this is aftermarket? If they are aftermarket, where can I get a set? I've been searching the web but can't find a match.

Thanks!
