Restore reliable xenon lighting with the Standard Ignition High Intensity Discharge (HID) Lighting Ballast, MPN HID161. The ballast supplies the high-voltage strike and then the regulated current a HID bulb needs to ignite and run steadily, so a failing original that causes flickering, dim, color-shifted, or dead HID headlamps can be swapped out. It is a direct-fit replacement for the 2004-2011 Mazda RX-8, 2007-2012 Mazda CX-7, 2009-2011 Mazda MX-5 Miata, 2013 Mazda MX-5, and 2013 Mazda MX-5 Miata — see the Buyer's Guide tab for engine-level details.
- DOT-certified: built to comply with Federal Motor Vehicle Safety Standards.
- Heavy-duty casing: rugged housing around the electronics supports durability.
- OE-matched circuitry: internal circuitry mirrors the OE design to support proper performance.
- Plug-and-play: installs without reprogramming.
If a failed ballast is the cause of your HID lighting trouble, this unit replaces it; diagnose the bulb, wiring, and igniter before ordering to confirm the ballast is at fault.
