In the United States, the 2012 Mazda6 uses two headlight configurations depending on trim: halogen projector headlights on base models and HID xenon headlights on the Grand Touring variant. Some overseas markets offered HID as an option or as standard on different trims. Verify the exact setup for your vehicle by checking the window sticker or VIN.
Headlight configurations by trim
The following outlines the common setup for North American-market models; regional differences may apply.
- Sport: Halogen projector headlights
- Touring: Halogen projector headlights
- Grand Touring: High-intensity discharge (HID) xenon headlights with auto-leveling; in some markets an adaptive lighting system (AFS) may be included
In short, the Grand Touring variant typically uses HID headlights, while the base trims use halogen headlights.
Bulbs and replacement considerations
Bulb types differ between the halogen and HID systems, and exact codes can vary by market. Refer to the owner's manual or a parts diagram for your vehicle to confirm the correct bulbs.
- Halogen headlights: use standard halogen bulbs (exact bulb code varies by market; common configurations for Mazda models include low-beam bulbs such as H11 and high-beam bulbs such as 9005, but verify for your region).
- HID headlights: require a ballast and HID bulb (commonly xenon D2S-type bulbs in many vehicles from this era).
When replacing bulbs, consider the need for proper alignment and, if upgrading, ensure any modification complies with local regulations.
Summary
The 2012 Mazda6's headlights depend on trim and market: halogen projector headlights on base trims and HID xenon headlights on the Grand Touring trim in the U.S., with some overseas markets offering HID as an option. Validate with your VIN/window sticker to confirm the exact setup.
