Headlights problems of the 2000 Mazda 626

I am actually writing to report a problem I have with other vehicles on the road - specifically suvs and other small trucks, as well as vehicles using xenon lamps in their headlights. These vehicles have on numerous occassions blinded me while driving; the xenon lamps from oncoming traffic, and the trucks from behind. The xenon lamps are too bright for an oppossing driver to see past at night; frequently, it has been my experience that they are as bright or even brighter than high beams of most normal lamps. The trucks are a problem from even quite a distance away for drivers of sedans and smaller cars; when my husband drives, the headlamps of trucks reflect directly into his eyes through the rearview mirror (he is 6 ft tall, average height of a man in this country), as well as from the sideview mirror depending on the position of the truck behind us. I would strongly urge you to consider banning the xenon headlamps altogether, and to consider forming some sort of regulation that would dictate the height of headlamps of all vehicles (excepting semis) to within a range that will not interfere with the driving capabilities of any drivers on the road.
