Sylvania 9003ST Silver Star Twin Pack High Performance Halogen Headlight Bulb

It would be nice if they put the "not expected to last 12 months" label on the package! Had 2 sets on my Accord (low beams only), both lasted 9-10 months. I don't have driving lights and do minimal night driving. My factory lamps lasted 5 years, actually only one blew and I just put the other back in. Will stick with OEM.

very bright white light. good visibility for both auto and motorcycle use. only complaint is they do not last anywhere near as long as regular bulbs and they are certainly more expensive. given how well you can see with them though, I'll never go back to regular headlight bulbs.

Good news: Quality of light a noticeable improvement over standard halogens. Pattern of low beams, 'throw' of high beams, higher color temperature and brightness, all are good.
Bad news: Purchased Sept. 2007, both low beams burnt out with one week in Jan 2008. Lifetime: ~4 months!!! Replacement lamps are NOT Silverstars.
Price: $39 (pair) at Auto Zone. Standard bulbs: $18 (pair) at NAPA.
Standard halogen life is probably closer to 2 years.
Verdict: great light, but you'll pay a very high price to enjoy it.

Of six bulbs installed in three vehicles, four have burned out in less than eighteen months. As mentioned by others, Silverstars are whiter, but not necessarily brighter. Because of this, they blind oncoming traffic. That coupled with their short-life, makes them unsafe. After blowing another one this morning, I just pulled them from all my vehicles and threw them away.

I must say that I have only had these for a month, so I cannot attest to their longevity. I can say however that the light quality is outstanding and immediately noticeable from standard bulbs. They really show up well in snow conditions.
