I just installed the GE Nighthawk bulb prior to Oysterfest 2010. I am pleased to report that the bulbs performed better than the Sylvania Silverstar that I had put in a few months ago. I have not tried the Silverstar Ultra so I can't say about them - but I am very pleased with the results of the GE Nighthawk. I can drive at night again.
I was disappointed that I could not find a local parts house that had GE lights in stock. Had to order from Amazon for about 60 bucks for the set.
Thanks for the heads up Orren!
Roger that!
