2005 lexus es 330 developed problems with the high intensity discharge headlamps. the low beam headlights do not provide adequate illumination, especially on roads with no street lights, reflectors or lane markings. there is a sharp cutoff of light about 40-50 feet in front of the car beyond which there is little or no light cast on the roadway surface. reflective signs can be seen farther away but one cannot help but overdrive the lights at any speed above 20mph because nothing on the road itself is illuminated. the low beams seem to be deliberately aimed at the ground 40-50' away. light in the 40-50' zone in front of the car is adequate. beyond that it is not. the car was purchased new in jan 2005 and the problem did not arise until 2-3 years later, or at least that's when i first noticed it. the dealer checked the lights and stated the high intensity lights could not be adjusted to raise the cutoff point(lights are self leveling) and that the lights were working normally. this is not a problem if there is oncoming traffic because their lights illuminate the road between my car and theirs. however on a dark street with no oncoming cars it's like driving into a pool of darkness past the 40-50 foot cutoff of light in front of the car. i have to use the high beams when on a pitch black road, but that's not a good solution. i will not buy another car without checking the performance of the lights on a dark road. lexus needs to fix this - it is an accident waiting to happen. mileage on the car in now in the mid 40s. this condition is ongoing, not intermittent. *tr
