I have used the Sylvania Ultra'* and they were a big help. They are about $40.00 for a pair. A year ago I had front end damage and both headlight assemblies were replaced with factory originals and I am very pleased with the results. Not only is the night driving greatly improved but the front end looks really good. Over time the bulbs and the reflectors tend to dull so even with new or brighter bulbs you will be limited to some degree. The glass tends to get sandblasted so you loose brightness there also. Replacing the headlight assembly turned out to be the best approach for me. It is not nearly as expensive as an HID setup and on vehicles that are as old as ours they can easily be a fire hazard. I would definitely stay away from any bulbs that are blue tinted in any way. Regardless of their claims, they do not help and actually make it more difficult to see at night. So, to recap, in my case the Ultra'* were an improvement but I am glad that I replaced the entire assembly because of the improved high and low beam output and it really looks good. Also, the brighter the bulb the sooner it will burn out.
