After driving my wife's new VW golf with the HID Xenon package, I was worried about the same thing. I wanted the ultra white light, but didn't want to blast oncoming traffic like all the Honda tuner guys. The trick for me was discovering that some projectors have an actuated metal blockout that remains in position when the beams are on low, and slips out of the way when full Hi beam is requested. A couple of used projector sets from a supplier, and the process began. EXCEPTIONALLY happy with the results.
H7 halogens for the hi/lo beams built from OEM Infinity SUV projectors.
The Hella foglights were from an OEM Lexus and I dig the yellow.
