I will use this product for night time driving in the metro area. I just installed the product today and have not had a chance to test the brightness of the lights so far. But everything checks out and I am sure I will not have any problems with them. They seem to be very durable and so easy to install on my late model car. Keep up the great work Advance Auto Parts with the fine products that you offer.

Contrary to the other 8 reviews here, for me these were very dim. I could hardly see the road after replacement of both bulbs in my 1996 Chevy S-10. My wiring all checked out OK. For a test I put one in alongside my original old but working HP6545 Sylvania bulb (with HALOGEN stamp on the plastic lens and body) and the old Sylvania bulb was brighter! Can't find the old bulbs sold anywhere. These are going back. I will look for other bulbs.

            Had to replace my headlight due to an accident and after replacing I realized how dim my original lights were so I replaced the other one as well.

              They are better than the standard Halogen bulbs, but don't expect a huge difference. The light output is brighter and whiter than the standard bulbs, but not by much...
