1. TRQ Driver and Passenger Headlight Assembly Set for Infiniti G37
| Bulb Technology | HID |
|---|---|
| Lens Material | Polycarbonate |
| Quantity | 2 Piece |
| Bezel Color | Chrome |
This TRQ two-piece headlight set replaces both driver and passenger assemblies on the Infiniti G37 and is sold as a matched pair for a direct-fit swap. Installation is aimed at the DIY owner: housings arrive pre-assembled, accept HID/halogen bulbs, and include chrome bezels and factory-style connectors so you can reinstall without major fabrication. Notable features include polycarbonate lenses and prewired harnesses that reviewers say line up with factory mounting points and provide a clean fit and finish. Practical benefits are improved front-end appearance and restored nighttime visibility compared with oxidized originals, plus TRQ supplies video guidance to simplify installation. Limitations to be aware of: some users report problems with beam aiming and nonfunctional adjusters on certain units, which can produce a cutoff that reduces long-range illumination until corrected, and a few buyers experienced inconsistent build quality. For buyers repairing an Infiniti G37, these are a cost-effective, mostly straightforward replacement but expect to verify and adjust beam aim after installation and plan modest mechanical work to access mounting points.
Best for: Buyers seeking a balanced, all-round replacement that restores appearance and basic lighting performance on an Infiniti G37 without paying OEM prices.
Less Ideal for: Avoid these if you need guaranteed factory-level beam optics out of the box or if you want a plug-and-play upgrade that requires no post-install aiming or adjustment.
- Direct-fit pair made for Infiniti G37 mounting points for driver and passenger sides
- Pre-assembled housings with factory-style connectors reduce installation steps
- Polycarbonate lenses and chrome bezels give a factory-like appearance
- Includes support content such as step-by-step installation videos
- Some units reported with nonfunctional or difficult beam adjusters leading to poor cutoff and reduced long-range illumination
- A small number of buyers noted inconsistent quality control between units
Verdict: A cost-conscious, mostly direct-fit replacement for Infiniti G37 owners that restores look and function but may require beam adjustment and careful quality checking.

Choosing the Right Infiniti G37 Headlight Assembly: Key Factors to Consider
Fitment and Mounting Points
Correct mechanical fit is the most important factor because improper mounting leads to alignment issues, rattles, or stress on adjacent panels. Ensure the assembly matches the Infiniti G37's mounting bosses, bracket locations, and bolt pattern exactly.
A unit that fits without modification reduces installation time and the risk of gaps that allow moisture ingress. If an assembly requires adapter brackets or drilling, expect added labor and potential warranty or bodywork concerns.
Electrical Compatibility and Connectors
Electrical compatibility covers connector type, wiring harness match, and whether the assembly supports the vehicle's original functions like parking lights, turn signals, and leveling motors. A matching connector prevents splicing and preserves factory wiring integrity.
Confirm whether the assembly accepts the same bulb types or provides integrated LEDs. Mismatched electricals can cause flicker, error messages, or require additional adapters, which complicates installation and troubleshooting.
Beam Pattern and Light Output
Beam pattern affects both visibility and glare for other drivers. Choose an assembly that reproduces the correct low- and high-beam cutoff and intensity for the Infiniti G37 to maintain safe, legal illumination.
Look for assemblies that specify beam type and testing standards. Consistent light output across left and right units helps ensure predictable aim and fewer adjustments at installation.
Lens Material and Seal Quality
Lens clarity and a durable seal directly influence long-term performance. Polycarbonate lenses treated for UV resistance resist yellowing, while high-quality gaskets and venting prevent condensation and water intrusion.
Poor seals or untreated lenses can lead to fogging, reduced light output, and the need for early replacement. Assess vent placement and gasket materials when evaluating longevity.
Installation Complexity
Installation complexity affects whether you can complete the swap yourself or need a technician. Consider required tools, whether bumper or trim removal is necessary, and if the assembly includes mounting hardware and instructions.
Simpler installs reduce labor time and the chance of improper reassembly. If aiming adjustments or leveling motor calibration are required, factor in additional time and possible alignment costs.
Bulb Support and Future Serviceability
Knowing which bulbs the assembly supports matters for maintenance and replacement. Assemblies that accept standard bulb types make sourcing replacements easier and more affordable.
If the unit includes integrated light sources, understand the expected service life and how repairs are handled. Clear access to replaceable bulbs or documented procedures for serviceability reduces long-term ownership complexity.
How We Chose the Best Infiniti G37 Headlight Assembly
We focused on replacements that prioritize correct fitment and reliable light output for the Infiniti G37. Primary evaluation criteria included mechanical fit to the vehicle mounting points, electrical connector compatibility, and headlight beam pattern and aim capability. We also assessed seal quality and materials to reduce the risk of condensation, plus lens clarity and UV resistance for long-term visibility. Ease of installation and the availability of standard bulb types or clear guidance on bulb requirements were included to reflect common DIY and technician needs. Durability under typical driving conditions, including vibration resistance and corrosion protection of mounting hardware, rounded out the selection factors. We excluded units that lacked explicit vehicle-specific fitment information, assemblies missing essential mounting hardware, or listings that did not specify beam type and connector details.
Our full evaluation process is outlined in our review methodology.
FAQ
How do I know if a headlight assembly will fit my Infiniti G37?
Check the product listing for explicit fitment to Infiniti G37 and confirm mounting point diagrams or vehicle year coverage. Look for matching connector types and notes on whether bumper or trim removal is required. If documentation is unclear, ask the seller or consult installation guides to verify fitment before purchasing.
Can I replace the headlight assembly myself?
Many Infiniti G37 headlight assemblies can be replaced by a competent DIYer using basic hand tools, though some jobs require bumper or trim removal. Factor in time for aiming the beams after installation. If the assembly includes leveling motors or complex wiring, professional installation may save time and ensure correct alignment.
What should I do if a replaced assembly fogs up?
Minor condensation often clears as vents equalize pressure, but persistent fogging indicates a compromised seal or damaged lens. Inspect gasket surfaces, vent ports, and mounting edges for gaps. Re-sealing or replacing the assembly may be necessary if moisture cannot be resolved through drying and reseating.
Do I need to adjust the beam after installing a new assembly?
Yes. New assemblies typically require beam aim adjustment to restore proper cutoff and alignment. Adjustments ensure safe visibility and prevent dazzling other drivers. Follow the vehicle service manual or use a level surface and wall method to set the aim accurately.
Are LED assemblies compatible with the Infiniti G37 electrical system?
Compatibility depends on whether the assembly is a direct-fit unit designed for the Infiniti G37 or an aftermarket conversion. Direct-fit LED assemblies that match the vehicle's connectors and mounting points often work without modification. Conversions may require resistors or adapters to avoid flicker or warning signals.
Conclusion
Prioritize assemblies that match the Infiniti G37's mounting and electrical connections, reproduce the correct beam pattern, and offer solid lens and seal quality. Those factors drive safety, longevity, and reduced installation hassle.Balance ease of installation and future serviceability against features like integrated light sources. Clear documentation on fitment and bulb types will help you avoid surprises and keep nighttime driving reliable.
