Keep your xenon headlamps firing with the Standard Ignition High Intensity Discharge (HID) Lighting Ballast HID130. This ballast steps up and regulates your vehicle's supply voltage into the high-voltage pulse needed to strike and sustain the arc inside HID (xenon) headlight bulbs. It installs as a direct-fit replacement for the 2012-2014 Audi A7 Quattro and the 2013 Audi S7.
- Mechanical job: converts and boosts battery voltage to ignite the xenon bulb, then controls current to hold steady light output.
- Direct-fit application: replaces the original ballast on the listed Audi applications.
- Signs this part may need replacing: flickering, dimming, delayed strike, color shift, or a xenon headlight that cuts out — if a failed ballast is the cause, this unit replaces it.
If a headlight problem points to the ballast, diagnose the cause before replacing, since bulbs, wiring, and igniters can produce similar symptoms.
