So let me get this straight, the different headlite housing does not actually increase light output, it actually limits it? Why on earth would anyone pay a lot of money, to reduce the light?
I want as much light out of my headlites as possible, and wider is good to, not everything is standing directly in front of you, that moose can be a bit off to the side and if the lights do not light it up, you stand a better chance of hitting it.
This seems a little like buying a good driving lite, and then taping a sheet of paper over the front of it, to reduce its lite output...............what a dumb idea that would be.
If your HID's are putting out too much lite, go back to the stock bulbs, and save a crap load of money and wasted time swapping out lite housings with expensive after market ones. I checked, and here in Canada, a good set of housing and the HID's bulbs, ballast etc is going to cost $1200 with taxes, and thatis not even installed yet. For just 20% of that price I can buy the kit, slip it into the stock housings, and get a lot more lite output.
