this helps alot, i was wanting to get the silverstars, but all the owners manual said was w5w or something, i am guessing that it is european or asian (the bulb numbers)? Thank you, my only problem is that silverstars are so freaking expensive! Over $18 for one bulb! But they work really well.
I suggest buying them in pairs. My first set lasted 8 months and went out within a week of each other. But yes, I love the light output so for me it's worth it, and about half of my high mileage driving is after dark.
