OEM G37 coupe headlights

Infiniti G37 Coupe Headlights for Sale. OEM G37 HID Headlight Assembly.

If you are looking for OEM G37 coupe headlights to replace a cracked or damaged housing, restore faded or hazed lenses, or return a repaired G37 to factory-correct lighting, sourcing a verified OEM assembly from a low mileage donor car is the most direct path to factory-spec fitment and output. At McClain Auto Part, we have been sourcing and selling used OEM exterior components out of Cleveland, Ohio since 2009. The Infiniti G37 coupe headlights are one of the most consistently requested lighting components we carry in the Infiniti platform.

G37 coupe owners come to us for a few reasons. Some deal with a cracked outer lens or a housing damaged by road debris. Others are restoring a G37 after a front-end collision and need a verified OEM assembly rather than a lower-quality replacement that does not match the factory lens profile and HID output. In addition, a group of G37 track and street builders sources clean OEM headlight assemblies as the foundation for custom projector retrofits, custom LED conversions, and wide body builds where factory-quality panel lines and mounting geometry are the correct starting point.

Whatever the situation, the goal is the same. A clean, fully functional factory G37 coupe headlight assembly that installs correctly and performs the way Infiniti intended.

G37 Coupe Headlight Overview

The Infiniti G37 coupe ran from 2008 to 2013 in the US market. The factory headlight system on most G37 coupe trim levels uses a high-intensity discharge HID projector as the primary low beam source. The HID system produces a higher output and a more precise beam pattern than a halogen reflector setup. As a result, it is one of the more desirable factory lighting configurations in the used sports car market.

G37 Coupe Generation and Trim Fitment

The G37 coupe uses the same basic headlight housing design across the 2008 to 2013 production run. The mounting geometry and outer lens profile are consistent across the production years, which simplifies replacement sourcing compared to platforms with mid-cycle styling updates.

The IPL variant uses a different front bumper configuration but retains the same basic headlight housing design as the standard G37 coupe. However, confirm your specific trim level before ordering. The standard G37 coupe headlight assembly is not the same as the IPL front end headlight configuration in all respects.

HID System on the G37 Coupe

The factory HID system on the G37 coupe uses a discharge bulb, a ballast to regulate the electrical supply, and an igniter to initiate the arc. All three components work together. A failed ballast produces a headlight that does not illuminate or flickers after startup. A failed igniter produces a headlight that does not fire at all. We document ballast and igniter function on every HID-equipped OEM unit before it ships. You receive that documentation before the order is finalized.

Why OEM Over Aftermarket Replacement

Aftermarket replacement headlight housings for the G37 coupe are widely available at lower price points. Most use lower-quality plastics, inconsistent lens profiles, and projector housings that do not match the factory beam pattern geometry. The result is frequently a headlight that fits loosely, produces a compromised beam pattern, and shows visible quality differences at the lens seams in person. A genuine OEM Infiniti G37 headlight assembly from a verified donor car gives you factory-correct lens profile, HID projector alignment, and panel line consistency that aftermarket replacements do not reliably replicate.

What Is Included

Here is what a typical G37 OEM headlight assembly package from McClain includes.

Standard With Most Units

• Complete G37 coupe headlight housing assembly
• HID projector housing, condition documented
• Outer lens, condition documented
• HID ballast, function confirmed on HID-equipped units
• HID igniter, condition noted
• Wiring pigtail and connector, integrity confirmed
• Mounting hardware where retained on donor vehicle

A Note on HID Bulbs

HID bulbs degrade over time even when the housing and ballast are otherwise functional. On higher mileage donor vehicles, the HID bulb is at or near end of life even when it still fires. We document bulb condition on every unit. Plan for a bulb replacement at installation if the donor unit carries significant mileage on the original bulb.

A Note on Adaptive Headlights

Some G37 coupe applications include adaptive headlight motor assemblies that steer the projector with steering input. Adaptive headlight motor condition varies by unit. Confirm your application’s adaptive headlight specification when you call and we advise on what is present and functional on the specific unit in current inventory.

Condition and Inspection

Every Infiniti G37 coupe headlight that ships from our Cleveland warehouse goes through a hands-on inspection. Headlight condition involves more than outer lens clarity. Projector condition, ballast function, connector integrity, and housing seal condition all affect how the unit performs after installation.

What We Check Before Every OEM Unit Ships

• Outer lens inspected for cracks, chips, hazing, and yellowing
• HID projector housing inspected for internal fogging, coating deterioration, and damage
• Reflector and projector bowl inspected for peeling or oxidation
• Housing body inspected for cracks at mounting tabs and around the perimeter
• Wiring pigtail and connector inspected for damage, corrosion, and terminal condition
• HID ballast tested for function
• HID igniter condition noted
• Adaptive headlight motor inspected where present
• Mounting tab integrity confirmed, no broken or repaired tabs
• Housing seal inspected for gaps that would allow moisture intrusion
• Overall condition graded and documented before packaging

Ballast function, projector condition, and lens condition are documented separately on every unit. You know exactly what you are getting before the order is processed.

Vehicle Compatibility

The OEM G37 coupe headlights fit the following factory applications:

• Infiniti G37 Coupe, 2008 to 2013, all standard trim levels
• Infiniti G37 Coupe IPL, 2011 to 2013, confirm fitment at time of order

Before ordering, confirm your model year and trim level. The G37 coupe headlight assembly is consistent across the 2008 to 2013 production run for most trim levels. Call us with your VIN and we confirm the correct unit for your specific car.

Retrofit and Custom Build Applications

A significant number of G37 coupe owners source clean OEM headlight housings as the foundation for custom projector retrofits, custom LED conversions, and wide body builds. The OEM housing geometry and mounting points give you a factory-correct starting point that aftermarket housings do not reliably provide. If you are using the housing for a custom build rather than a direct OEM replacement, tell us when you call. We advise on which units in current inventory are best suited for a retrofit or custom application based on condition.

Installation Notes

Direct Bolt-On Fitment

The factory G37 coupe headlights bolt directly to the OEM mounting points without modification. Access the mounting hardware through the engine bay and front bumper cover. Confirm all mounting points are secure and the wiring pigtail is fully seated before reinstalling the bumper cover.

HID System Reuse

For a direct OEM replacement, reuse your existing wiring harness and confirm the replacement unit’s ballast and igniter are functional before installation. If your original failure was a ballast or igniter issue rather than a housing or lens issue, confirm the replacement unit’s ballast tests correctly before ordering.

Adaptive Headlight Calibration

G37 coupe applications with adaptive headlights require calibration after headlight replacement. The adaptive motor position sensor needs to be reset to factory reference after any headlight assembly replacement. Confirm whether your specific car has adaptive headlights before ordering and plan for calibration as part of the installation process.

Headlight Aiming

After installing any replacement headlights, aim the low beam projectors to factory specification. A projector housing that is even slightly off aim creates glare for oncoming drivers and reduces your forward visibility. Most alignment shops perform headlight aiming with basic equipment. Confirm aim before driving at night.

Condensation

Minor condensation inside a used headlight housing is normal and typically clears after the unit warms up during operation. Persistent or heavy condensation after warmup indicates a housing seal failure. We note any evidence of seal failure or active condensation on every unit before it ships.
