Can't see anything when snows

Anyone have problem seeing the road when snow at night with HID? Last night I was driving North and couldn't see the road because my HID was lighting up all the snow coming down. It's like having high beam on and my light is aimed way down. (didn't re-aim after I reinstall the headlights) Had this problem last year too.
So I was driving with my fog/driving lights and parking lights alone.

Is this because I have halogen reflector housing?

That's just one of the inherent evils of blue-shifted light, more light scatter. I laugh whenever I read about someone installing HID fog lights. The next phase of your HID retrofit would be to motorize the headlights aim, so you can adjust them up or down from the cockpit, on the fly. Or maybe carry a roll of yellow-tinted Saran Wrap in the car, so you can filter out some of the blue light during snow or fog.

well i can tell you this, i use to live in alaska, about 2 months ago, (just moved to arizona,) and the the town i came from had about 80,000 people, and every new car pretty much every new car that had factory hids as an option had them, so, ooh and i had them on my jeep, and i didnt really have a problem with them.

Yeah, my HID work fine when it's snowing out at night. You got yours into halogen housings though. Mine are in A6 OEM xenon projector units and they have a sharp cutoff with very little light leaking above the light/dark cutoff, so I don't even light up the snow above my fixture height level on the car (except on the right a little, where the flare is). But if you got DOT halogen fixtures retro'd to xenon lightsource, then they likely bleed a lot of light above the headlight height all the way down the road in the form of the classic DOT 'fussbeam'. This also means you likely cause glare to oncoming traffic as well? You better check it out
