HID's are not exactly to blame, with proper application HID's have brilliant results. Use a 4300k HID with an applicable projector or with a compatible reflector housing and you'll notice how much sharper the cutoff is and the beam is well spread. However, people here use HID's in their Halogen Reflector Housings and Halogen Projectors, this is where things go wrong and HID's get a bad name.
Apart from this, the garbage Ballasts and Bulbs available in the local market are pathetic. Big names like Hella, Mitsubishi, Osram etc make one of the best Ballasts and Bulbs around the globe, manufacturers like BMW, Honda, Toyota, Subaru use these HID's as stock, these are far superior to the Chinese crap and come for a good price tag, but then quality comes for a good price tag too
