I have the Silverstars and they are nice. Not as nice as HID's, but still, they are decent for ~$40 from Autozone. If and when they burn out, I will try and replace them with a set of Phillips Vision Plus. Not sure if they make our size, but they are a popular european bulb, especially among my fellow VW guys and girls. They are white like the Silverstars, but they have been proven to increase the length of the beam without increasing glare. Check out
www.pgperformance.com and take a look at them. Once again though, I'm not sure if they make a bulb in our size.
