HID is a pratically a bulb that is powered by a ballast and the advantage of that is that the bulbs are alot brighter and dont cost much
Angel eyes are the rings that go inside the headlight they do look nice but wont help as they are only for the looks. the distadvantage is that you have you open up the head lights to put them in. where as the HID kit only takes 10 mins at most to fit.
i have 8000k HID kit and i would say they are the best mod and makes the car look a lot better mate.
