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

BULIAZY 2-pack D2S xenon ballast kits include igniters and D2S bulbs to replace faulty HID headlight systems on compatible Infiniti and Nissan vehicles.

When a xenon headlight flickers, fails to ignite, or reports a ballast error, replacing the ballast assembly plus igniter and bulb is often the quickest way to restore proper illumination. These BULIAZY kits are engineered as direct-fit replacements for many Infiniti and Nissan models, sourced to match common OEM part numbers and to install without coding or extra configuration.

Which vehicles will these ballast kits fit?

These ballasts are matched to the common part numbers used in numerous Infiniti and Nissan cars from the early 2000s through mid-2010s. They are designed to be compatible with either the left or right headlight and supplied complete with igniters and D2S bulbs so you can replace a failed unit with minimal additional parts.

• Fits many Infiniti models: G35/G37, M35/M45/M56, FX35/FX45/FX50, QX56, QX60/JX35 and more.

How reliable and safe are these replacement ballasts?

The BULIAZY ballast assemblies are built with aluminum housings and through-hole electronics to meet or exceed factory performance expectations. The units include multiple electronic protections to guard the headlight system and improve long-term reliability under normal driving conditions.

• Six protection features: over-voltage, under-voltage, overheating, no-load, short-circuit, and reverse-connection safeguards.
• Aluminum construction helps resist vibration and dissipate heat for longer life.
• Sealed internal components reduce oxidation and aging caused by moisture and contaminants.
• Designed to be a direct physical and electrical replacement—no programming needed.

What should I check before ordering or installing one of these kits?

Diagnosing the root cause of a headlight failure prevents needless part swaps. The ballast is the most common cause, but bulbs and wiring faults can also create the same symptoms. A quick swap test can confirm whether the ballast is the failing component.

• Move the suspect ballast from the non-working side to the known good side; if the problem moves, the ballast is defective.
• Inspect bulb condition and connector pins for corrosion or damage before concluding the ballast is at fault.
• Ensure the vehicle’s headlight connectors and fuses are intact to avoid installation errors.
• Contact seller support if unsure; BULIAZY offers response assistance for troubleshooting within 24 hours.

How easy is installation and what’s included in the kit?

The kits are supplied with both xenon D2S bulbs and the igniters already matched to each ballast, making installation straightforward for DIYers or technicians. Because these units are designed for plug-and-play replacement, you generally won’t need specialized programming tools.

• Comes as a 2-set kit: two ballasts, two igniters, and two D2S bulbs—ready to swap.
• Mounting points and electrical connectors match original equipment layouts.
• No coding required—replaces failed ballasts that fail electrically or mechanically.
• Fits either left or right headlamp assemblies for flexible installation.
