I installed clear Osram Silverstar H7 bulbs about 4 or 5 years ago. I have never seen the clear version in the US. For some reason premium bulbs cost a lot more in the US. Two Osram (=Sylvania) Silverstar H7 bulbs cost under 20 Euros, which is a lot less than the silly blue Sylvania Silvania Silverstars cost in the US. There are some online vendors that sell the clear OSARM version, but they are overpriced, too. Pick up a few sets on a Euro trip, or have a friend bring some back.
Before the Silverstars, I used clear Phillips Vision Plus bulbs in low and high beams. The Silverstars are marginally whiter, but with age all halogen lights get increasingly yellow. Neither the Osram or Phillips bulb burns out quicker than a regular bulb. The extra brightness comes only from optimized placement of the tungsten filament in the exact focal point, which makes the bulb optically more efficient.
A premium bulb in a DOT-compliant headlight that's older than about 6 years is pearls before swine, because the lack of auseful beam pattern is the main problem, which isn't being addressed by a brighter bulb. Newer DOT and DOT/e-code hybrid lights can make use of premium bulbs.
