I switched my '97 Buick over to Sylvania Cool Blue (bought at Walmart) from the ones that were in there, and my visibility range is almost six times what it was. Silver Star lights are even brighter than Cool Blue, but cost $20 a piece. I aligned my own headlights by using a pair of needlenose pliers to turn the adjusters. Just park in a garage facing the door, three feet away, and measure from the floor to the top of the light assembly. The low beam lights should have a distinctive line at the top of the field of light projected on the door. Adjust the lights until this line is 1/8 inch below the height of the top of the headlights when parked three feet away. If you want to get really technical about it, you want them pointed down at an angle of 4 to 6 degrees. Here in the US, most places don't care about how they're angled, and there are no restrictions on what bulbs you can use.
