I will give a second (or third or whatever it is) to JJ at Retroshop.
Great product, great service.
As to high beam versus low beam, EVERY proper projector assembly will do both low and high. Yes, it's called the low beam position, but that's because it's the only place you get low beam.
Some of you (those that are over 40 or so) may remember the days of quad headlights. This was when there were no brand/model specific headlights - all cars used one of two different systems: either 1) 7" diameter headlight per side that had both high and low beam filaments, or 2) 5-1/4" (?) headlights per side; one with both high and low beam filaments, and one with high beam only.
The current Ram quads and Projectors are functionally similar. The "low beam" bulb is always on when the headlights are on. In the "Quad" (technically they are both quads, but we call the reflector halogen "quads" to differentiate them from the projectors), the low beams stay on when the high beams fire. However, in the Projectors, while the low beam bulb stays on and at the same power, a shutter that is blocking part of the light in low beam mode is lifted, essentially turning it into a high beam as well, kinda like the old round quads.
The bottom line is that AFAIK every factory HID projector installation is a "low beam only" application, where the HIDs provide both low and high beam, but they ALSO have halogen high beams to compliment the HIDs.
So, no, if you get HID projectors (and I strongly suggest you don't even think about putting HIDs into reflector housings), you don't need to also upgrade your high beams. You can, sure. But I really don't see any need. I got the Morimoto projectors from JJ with 50w bulbs and am very pleased with them. They're definitely not quite as good as my CLS550, but that cost twice as much as my Ram so what can you expect?
