DO NOT BUY SYLVANIA SILVERSTARS!
Can't say it enough. Sylvania Silverstar bulbs are TINTED BLUE. Tint decreases light output, mmmkay? Of course, they give the "HID look" that all the ricer kiddies are after these days.
If you want more light without gimmicky blue tint, get "high efficiency" +30/+50 bulbs like Philips VisionPlus, Sylvania XtraVision, or GE NightHawk. These bulbs have more output than standard bulbs, and more importantly, NO TINT.
Personally, I have the IPF H4 lenses and Sylvania XtraVision bulbs, with a custom heavy-gauge wiring harness. Getting headlamps that accept H4 bulbs gives you many more upgrade options than the sealed-beam units.
My recommendation:
1) Hella, Cibie, or IPF H4 headlamp units
2) Wiring harness + relays
3) Philips VisionPlus or GE Nighthawk bulbs
4) High-quality (Hella, Cibie, etc.) driving lamps mounted on bumper or roof rack
5) High-quality fog lamps mounted on or under bumper
