Re hid lights: my vision is impaired in the evening when a car comes along with the high intensity discharge lights. For me it is really a very serious problem. My safe driving is also affected when hid headlights shine in my rear view mirror. They are a serious safety hazard for many of us and might already have been the cause of accidents.
