2 Pack HID Headlight Ballast with Igniter & D2S Bulb - Direct Fit

In this review the 2 Pack HID Headlight Ballast with Igniter and D2S Bulb is evaluated as a direct replacement option for a range of Infiniti and compatible Nissan and Mazda models. The bottom line: this kit is for owners who need to restore consistent xenon lighting quickly and affordably, because the single biggest reason to buy is the plug-and-play replacement that restores stable voltage and prevents the flicker, buzzing, and color shifts caused by a failed ballast. It is presented as a practical repair kit rather than an upgrade, and it addresses common failure modes that otherwise lead to repeated bulb losses.

Key Features

• Complete kit: Includes two xenon ballasts, two ballast igniters, and two D2S bulbs so both sides can be serviced at once for matched output.
• Electrical protection: Built-in safeguards against over voltage, low voltage, overheating, no-load, short circuit, and reverse connection help protect the new bulbs and wiring harness.
• Direct replacement: The modules are designed as plug-and-play replacements for the listed OE part numbers so no programming or coding is required during installation.
• Performance bulb: Each D2S bulb is 35W, rated at about 3200LM and 6000K, delivering a crisp white beam for improved nighttime visibility.
• Durable construction: Uses surface mount and through-hole components with IP68-level protection to resist moisture-related failures that commonly kill ballasts.

Who It's For

This kit is best for Infinity owners (examples include EX35, FX35, G35, G37, Q50 and QX models across the listed years) and owners of compatible Nissan or Mazda models who are experiencing dimming, flickering, buzzing, or color changes in their xenon headlights and want a straightforward repair. It is also suited to DIY mechanics who prefer replacing both sides at once to ensure matched output and avoid repeated trips to replace a second failed ballast or bulb.

It is not aimed at users looking for aftermarket styling upgrades, higher output racing lamps, or LED conversions; those buyers should look for performance kits specifically marketed for increased lumen output or different color temperatures rather than an OE-style ballast replacement kit.

Pros & Cons

Pros

• Comprehensive kit restores both ballasts and bulbs for matched light output and simpler installation.
• Multiple built-in protections reduce the chance of rapid failure due to electrical faults or reverse connection.
• Plug-and-play form factor fits the listed OE part numbers so installation is straightforward without coding.
• D2S 35W bulbs provide a clear 6000K white light that improves nighttime visibility over aged bulbs.

Cons

• Not an upgrade for higher output or different lighting technologies; this is a like-for-like replacement rather than a performance conversion.
• Compatibility is limited to the models and years listed, so confirm fitment before ordering.

Our Verdict

The 2 Pack HID Headlight Ballast kit is a practical, cost-effective fix for owners whose xenon headlights are flickering, buzzing, or changing color because of ballast failure. It is good value for anyone who wants a matched pair replacement with built-in protections and no coding required, though it is intended as an OE-style replacement rather than a performance upgrade.

Frequently Asked Questions

Will these ballasts fit my vehicle?
They replace the listed OE part numbers and are compatible with the Infiniti, Nissan and Mazda models and years specified, so verify the part numbers for your vehicle before purchase.

Do I need to program or code these units?
