I emailed Sylvania, so I'll have to wait and see if anything happens there. This is my first year with the bus and it's awsome. I am still at the age where I have to hookup all of the vehicles that I drive, to set them apart from the rest and the headlights on the bus needed an upgrade, but since I don't own the bus, it was easier just to throw on a set of Silverstars,and they worked great until they blew out on me. I like the way they look on the bus, but a set of diamond backs would look even better, maybe someday I'll get a set, but for now this is what I am working with.
