Hella 178560801 HID Xenon Headlight Bulb - D1S 4300K 35W Single

The Hella 178560801 is a D1S High-Intensity Discharge (HID) xenon headlight bulb rated at 4300K color temperature and 35 watts, sold in single-pack packaging. Designed as a direct OEM-quality replacement for vehicles equipped with D1S projector-type HID headlamp systems, this bulb delivers powerful, focused illumination for enhanced nighttime visibility.

HID technology generates light through an electrical arc inside a gas-filled xenon capsule, producing significantly more light output than conventional halogen bulbs while consuming less power. At 4300K, the bulb emits a crisp, neutral white light closely matched to factory OEM HID output — providing excellent road clarity without excessive blue tint.
