I have had good luck with the new Sylvania Silverstar Ultras in my Sc2, will plan on using them on my '07 ION.3 soon as I save up the . for the pair. Be sure to get the Ultras, they last longer, don't get as hot and put out more light. I don't know about the inside of the lens, but if the outside of the headlight becomes cloudy, try Maguire's Plastix, works great on keepin them shiny too.
