Fire up your xenon headlights with steady, regulated power using the Standard Ignition High Intensity Discharge (HID) Lighting Ballast (HID141). This ballast steps up and controls the voltage that ignites and sustains the HID bulb's arc, and it drops in as a direct-fit replacement for the 2013-2014 Audi A4, A4 Quattro, A5, A5 Quattro, S4 and S5, plus the 2013-2015 Audi Allroad. See the Buyer's Guide tab for engine-level details.
- DOT-certified: built to comply with Federal Motor Vehicle Safety Standards.
- Heavy-duty casings: rugged housings surround the electronics for durability.
- OE-matched circuitry: internal circuitry follows the OE design to support proper performance.
- Plug-and-play: designed to install without reprogramming.
When an HID ballast fails, you may see a headlight that flickers, cycles on and off, glows the wrong color, or stops lighting altogether. If a failed ballast is the cause, this unit replaces it to restore power delivery to the HID bulb. Diagnose the cause before replacing.
