Philips which is an OEM suppler of HID bulbs/ballast rates their bulbs/ballasts at approx 2000-2500 hours. It honestly depends on how often you drive with your lights on. Generally speaking though HID bulbs do last longer than halogen bulbs as they do not have a filament. As a result, they are not susceptible to road vibrations which is usually the cause for most halogen bulbs to go out. In terms of aftermarket HID kits, it really depends on the quality of the components used in the kit you purchase. Stick with reliable vendors when purchasing products for your vehicle.
