bmw e46 coupe & sedan {Xenon} halos

The BMW E46 coupe xenon headlight is a high-intensity discharge (HID) projector headlamp designed to deliver brighter, whiter, and more focused illumination than traditional halogen units. Featuring a xenon arc bulb paired with an integrated ballast/igniter, it provides excellent nighttime visibility and a crisp, modern beam pattern. Many versions include auto-leveling motors for proper aim under varying loads, and some models offer bi-xenon functionality, using a movable shutter to provide both low and high beams from the same projector. Its sleek lens and projector design enhance the E46 coupe’s distinctive front-end appearance while offering improved performance, longevity, and premium OEM styling.
