Silverstar 's are an OK upgrade, but the Silverstar Ultra's really do the trick - 40 % increased down road visibility, Increases side road visibility by 50%, up to 50% brighter than a standard halogen. They last a bit longer than the basic Silverstars. I like the Ultra's, I think they have kept me from hitting a few critters. I know that spike bull on Highway 20 is greatful I had them, . . . LOL.
