>ebay hids on non projector headlights SUCK! i pity all those who drive in the lane opposite of mine, for they shall see nothing.
The problem is not whether it's a projector, but whether the housing is made for HID bulbs. A bulb which generates light by arcing lightning between two electrodes is entirely different from a bulb which generates light by heating up a tungsten filament. The intensity, geometry, even the orientation (HIDs typically arc vertically, while halogens typically have their filament horizontal) are at odds.
HIDs can work in reflector housings just fine. The Altima 2.5s has HIDs in reflector housings, for instance.
On the other hand, sticking an HID into a projector housing meant for a halogen bulb will produce glare and mis-aimed light. It might be less noticeable because modern projectors tend to have a sharper cutoff than US reflector housings, but it's still not suitable. Sticking an HID into a E-code (European spec with sharp cutoff) halogen reflector housing will produce similar results to putting on in a projector. Doesn't mean it's good.
Put HID bulbs into HID housings. Put halogen bulbs into halogen housings. And don't mix.
