Just have to say I love this site. Recently upgraded lights with Sylvania Cool Blue Lights (3500 Kelvin v.s. Stock 3200) and noticed a huge difference in brightness. Much brighter and no longer dog pee yellow. Canadian Price $12.00 (~ $7.50 US). Went to the USA for weekend and found Silverstars and replaced low beams (4000 Kelvin) and noticed even more of an improvement in whiteness. $24.00 at Checker Auto parts. ($38 Cdn). Was suprised to see Cool Blue's priced at $16 US (~$25.00 Cdn) which was considerably more expensive than in Canada. I can't believe that something is actually cheaper in Canada!!!!! Overall, very happy with the Silverstars for lows but not enough to replace Cool Blue's in highs and fogs. Friend at work had Cool blues in SUV and lasted 3 years before burning out. Hope I have the same luck.
