The Retrofit Police... do not try to prove them wrong. They LOVE to deter people from doing retrofit, even if they will never, ever see you on the road, with all your dreaded glare and their burned retinas. Makes me laugh everytime, like if it was the most important thing in the world.
The thing is, I've seen simple retrofit in halogen projectors, and it does not produce any more glare than all the stock HID in projectors I see passing by. Sure, I would not do a retrofit in a stock non-projector headlamp, but that is not the point here. Do what you have to do, and thanks for sharing the information, and just let them do their things.
