I bought my headlights from the same place (katmac) and I was pleased with them overall. Just throw those blue colored bulbs right in the trash and get some regular bulbs. I was curious about the Silverstars myself and bought 1 silverstar and 1 regular and yes, with both in my headlights at the same time I did notice a "slight" difference between the two, but not nearly enough to justify $40 for 2 as oppose to $14 for regular bulbs. And I wouldnt suggest buying the "plasma" H3's, just use the ones from your old headlights.

Just make sure you get them aimed good and with headlights and foglights on at same time, there is plenty of light on the road.
