Actually they could and they do, if you aim them properly.... glare has nothing to do with the product it has to do with your headlight and how well you aim that. As mentioned many times our HID are made with a cut off and when aimed properly the results are very nice. Our products surpass DOT, SAE and ISO9001 testing here in America. THe glare you see are just the angles that are taken, I bet if you took a pic head on at your car there would be glare in the pic unless you dial it down in photoshop.
