HID projectors are not same as putting HID bulbs in stock Xterra OEM reflector housings.
Instead of reflecting more light in all directions, the light is projected forward in first place.
HID vs LED
LED projectors need deeper assemblies than Xterra has room for.
Both HID and LED are used in modern OEM and aftermarket quality assemblies
Headlight assemblies
Morimoto quality components are inserted into OEM or Eagle Eye housings, based on your preference. 5000K, 5500k and other Morimoto bulbs are available
