Looking up the Sylvania Silver Star bulbs, the last ones that I purchased were the Ultras (with the gold stripe on a red package - $50 for 2). Prior to those, I believe were one of the Philips H7 bulbs, but not positive which ones ($40 for 2). The last one the mechanic put in did not list the brand on my receipt, but I could probably get the info. I do know he stated it was a high end bulb, and it did outlast either of the previous bulbs.
