The term angel eye again came from the BMW line of cars. Many of the modern BMW vehicles have an LED ring that circles the low and high beam lights. These LED rings are separate from the headlights themselves and really don't provide much as far as lighting the road. However, they do look very exotic and can be used as Day-time Running Lights (DRL), parking or signal lights depends on how you connect them. Many of the custom aftermarket projector headlights come with either one or two angel eyes depending on the size of the lens. Likewise, the term halo is referring to the same LED ring.
