        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.

        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.

          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...
