I've used the OSRAM Silver Star and longer lasting Ultra Star H4 headlight bulbs for years. They do put out better light than sealed beam bulbs but appears Sylvania just made statement without empirical proof. Lawyers have negotiated a $30M settlement for false advertising. I'm sure lawyers will get the bulk of the settlement. The Silver Stars seem to last 13 months - the Ultras 24 months. Although I've gotten several rebates for purchase I haven't received a post card from Sylvania. Use the link to be part of the settlement.
Hoping to get enough $ for an egg samich!
