Daytime running burned out and a quick google search came up with them being leds built into the lens itself. Replacement would involve a new assymbly, there also appears to be a common failure problem with these and no recall as of date. So i figured i'd come here for some facts are they non replaceable leds? If not what do i need? With no listing on the philips bulbfinder i'm thinking it is built in leds, however i realize they don't have a complete data base there as good as it is
