I put silverstar bulbs in my wife's van and was disappointed with the lack of longevity.
Bulb change won't do what I want to do. I want to light up out in front when driving at night at highway speed (55 mph).
I had the same problem with my Jeep Wrangler. The headlights were just dim. After a little research I converted mine to accept projector style headlights. The difference was amazing. The distance probably doubled and while the light has a hotspot right where you want it, it also has a very wide beam to go with it. I'm very happy with the results.
