I started using these PIAA bulbs about 6 years ago when one of my OEM low beam bulbs burned out. They are significantly brigter than the OEM bulbs and make a notable improvement in night driving. I used the Sylvania Silverstar bulb in my other car for which PIAA does not make a bulb, and they aren't as bright. You won't mistake these for HID Xenons, and they are much more expensive than OEM replacements, but the added saftey and performance is worth it. I've installed them in my high beams and fog lights too. My one complaint is that they do not last as long as the OEM bulbs - only about 1-2 years. Coincidentally, four have gone on me in the last few months.
