What's the difference between HID houisng and non-HID housing? Is it possible to buy just one HID housing (housing only)? Help me out guys...I need a right HID housing for my car.

 

on the hid housing theres a circle around the projector and on the non hid the lines go straight through if that makes sense to you. and yes if you can find someone willing to order just one side it is possible i know my friend only ordered one side.
