Angel Eyes, also known as "halos," are accessory lights that are installed or integrated into a vehicle's headlight assembly, to encircle the low or high beam headlight. They do not replace the headlight or any other lights, they are simply accessory lights, for cosmetic purposes, or to be used as a DRL.

Originally designed and first used by BMW, the unique look was desired by many in the aftermarket community, leading to a surge of lighting components available to be installed into existing headlights to create the same look. There any many different types of angel eye components on the market, utilizing different technologies to create the "ring of light" effect.

These rings are available in a number of colors- you just need the right LED, and the correct ring size. You can even use four-lead RGB 5mm LEDs to create multicolor effects. They are extremely durable, and should last a very long time, but they are somewhat unrefined, as the "notching" process is often accomplished with a rotary tool, such as a Dremel.
