GDMOTUPART HID Headlight Ballast Kit 2-Pack with Igniters & D2S Bulbs — OEM Fit, Plug-and-Play

If your HID headlights are flickering, slow to light, or dimming, this GDMOTUPART two-piece ballast kit provides a drop-in replacement designed to match original equipment fit and function. The package includes two ballast control modules, two igniters, and two D2S xenon bulbs so both headlight circuits can be serviced at once. Each unit is manufactured to meet stringent standards, tested before shipping, and labeled to align with common OEM part numbers so you can replace aging or failed components without modification.

How will this kit improve my headlights on the road?

Replacing failing ballasts and igniters restores consistent ignition and steady light output, eliminating flicker and delayed start. The included D2S bulbs pair with the ballast to deliver the color temperature and lumen output intended for your original xenon system.

• Restores reliable ignition and eliminates flickering
• Returns brightness to factory-level lumen output
• Improves beam stability for consistent nighttime visibility
• Packaged as a complete left-and-right replacement set

Will these parts fit my Infiniti or Nissan model?

These modules are engineered to fit a wide range of Infiniti and Nissan vehicles that used D2S xenon systems. The listing corresponds to several OEM numbers and common platform applications, but you should verify the part number on your original ballast or consult your service manual to confirm compatibility before ordering.

• Fits many Infiniti models: G35, G37, FX35/FX37/FX45/FX50, QX60/QX56/QX70/QX80, M series, JX35, Q50/Q60/Q70
• Also compatible with Nissan models: 350Z, 370Z, Altima, Maxima, Murano, Rogue, GT-R, Quest
• Cross-references include OEM numbers like 28474-89904 and 28474-8991A
• Double-check year and original ballast label for exact match

How difficult is installation — do I need special tools or coding?

Installation is intended to be plug-and-play with no special programming required for systems designed to accept direct replacements. Most installations involve removing the factory ballast, unplugging connectors, and fitting the new unit into the original mounting points. If your vehicle has been modified or uses aftermarket controllers, extra steps might be needed.

• Designed for direct replacement with factory connectors
• No ECU coding or software updates required for standard systems
• Typical tools: basic hand tools and safety gloves
• If unsure, consult a qualified technician or service manual

What build quality and protections are included?

GDMOTUPART manufactures these ballasts to approximate OEM durability, using components that control voltage and protect the HID circuit. Each unit undergoes bench testing to ensure stable output and to reduce the risk of premature failure compared with cheap, untested alternatives.

• Voltage regulation to protect bulbs and electronics
• Durable housings designed for under-bumper or engine-bay environments
• Pre-shipment testing for functionality and safety
• Complete kit reduces troubleshooting by including igniter and bulb

Who is this for: This two-pack GDMOTUPART HID ballast kit is aimed at owners of compatible Infiniti and Nissan vehicles who want a reliable, OEM-style replacement for failing xenon headlight components. It's suitable for DIY mechanics who prefer plug-and-play swaps as well as professional installers needing a tested, ready-to-fit solution. Always confirm the original part number and model year before purchase to ensure proper fitment.
