BULIAZY D2S Xenon Headlight Ballast Kit with Igniters & Bulbs — 2-Pack Direct-Fit for Infiniti/Nissan, Plug-and-Play Reliability

This complete ballast replacement kit from BULIAZY is built as a direct-fit option for a wide range of Infiniti and Nissan vehicles, offering a ready-to-install solution when a xenon headlight flickers, fails to ignite, or shows ballast-related faults. The set pairs high-grade aluminum housings and through-hole electronic components with built-in protections to help the lighting system operate reliably without coding or extra programming.

Which vehicles will this ballast and D2S bulb kit fit?

The BULIAZY kit is designed to replace OEM parts on many Infiniti and Nissan models spanning early 2000s to mid-2010s production years. It matches common OEM part numbers and fits left or right headlight assemblies where D2S xenon systems were factory-installed.

• Infiniti: G35/G37 (coupe and sedan), M35/M37/M45/M56, FX35/FX45/FX50, QX60/JX35, QX56/QX70, Q45 models in listed years
• Nissan: 350Z, 370Z, Altima, Maxima, Murano, Rogue, GT-R, Quest where D2S xenon headlights were used
• Directly replaces part numbers such as 28474-89904, 28474-89907 and related variants

How do the built-in protections help keep headlights working?

Each BULIAZY ballast includes six electronic protections that reduce the chance of immediate failure and protect connected components. These safeguards help the module tolerate common electrical issues encountered in automotive environments.

• Over-voltage and low-voltage protection to shield circuits from unstable power
• Overheating protection to prevent thermal damage in hot conditions
• No-load and short-circuit protection for safer fault conditions
• Reverse-connection protection to prevent damage from incorrect wiring

Will this ballast require programming or special tools to install?

Installation is plug-and-play for most compatible vehicles and does not require ECU coding. The BULIAZY ballasts are made to meet or exceed OEM specifications so they can be swapped into the original mounting points with the factory connectors.

• No programming or dealer tools needed for standard replacements
• Fits either left or right headlamp housings with D2S bulb systems
• Includes D2S bulbs and igniters so the kit is complete for a two-side replacement

How can I diagnose whether the ballast or another component is faulty?

A simple swap test helps identify a failing ballast: move the suspect ballast to the opposite headlamp and check whether the problem follows the unit. If the light works after swapping, the ballast was the likely cause; if not, bulbs, wiring, or connectors may need inspection.

• Swap ballast between working and non-working side to isolate the fault
• Check bulb seating, connectors, and ground points if swapping doesn't restore function
• Contact BULIAZY support if you need guidance — response promised within 24 hours
