Yes, a projector housing would be ideal. The way I aimed my light initially was blinding on-comers, as my wife will attest to; but with some adjusting I found an angle that did not blind her. If there was an affordable aftermarket projector available, I would buy it. But since there isn't, I think this is a good alternative. I no longer feel like I am over-driving my headlight now. I am convinced I am not blinding anyone, and I am skeptic that if I was, someone would focus on the light and swerve towards it or something. We all have shared two lane roads with obnoxious KC/HID festooned cars, but how many of you have hit them because of the distraction?
I am not trying to start an argument. Just my 2 cents.
