Give Daniel Stern a call.

Avoid Silverstars and ESPECIALLY avoid HID kits. Actual lumen measurements by integrating sphere have shown Silverstars to have the least lumens of Sylvania's lineup, lower than stock even. The physics are simple, you can not increase brightness by adding a filter to a bulb that removes light. They also have the highest cost and the lowest lifespan. They at least maintain beam pattern, which can not be said for HID kits. There are ways to legally and safely retrofit HID headlights onto a vehicle, stuffing an HID capsule in a housing designed for a halogen bulb is not it.

Seriously, give Daniel Stern a call. danielsternlighting.com
