Specifications and Maintenance of Infiniti FX35 Lights
Proper maintenance ensures optimal performance, longevity, and safety of your Infiniti FX35 lighting system. Follow these key maintenance procedures:
Regular Inspection and Cleaning
The Infiniti FX35 LED lights require routine inspection for wear, damage, or moisture intrusion. Clean with a soft, dry cloth to remove contaminants.
Caution: Never use abrasive materials, sharp tools, or harsh chemicals when cleaning light assemblies as these can damage the lens or housing and compromise waterproofing.
Proper Bulb Replacement
Always use manufacturer-specified bulbs that match the correct type, wattage, and color temperature. Higher wattage bulbs can overheat and damage housings.
Pro Tip: When handling halogen bulbs, avoid touching the glass with bare hands. Skin oils can create hot spots that lead to premature failure. Use gloves or a clean cloth when handling.
Sealing and Gasketing
Regularly inspect all seals and gaskets around light assemblies for cracks or deterioration. Replace worn seals to maintain waterproofing. If moisture is found inside a housing, remove the bulb, dry thoroughly, and replace damaged seals.
Alignment and Adjustment
Headlights may require realignment after bulb replacement or other maintenance. Improper alignment reduces visibility and can create dangerous glare for other drivers.
Adjustment Method: Use a proper alignment tool or check aim against a wall to ensure headlights are properly adjusted according to manufacturer specifications.
Lens Cleaning and Restoration
Over time, headlight lenses can become cloudy or yellowed, significantly reducing light output. Use a lens cleaning kit or mild polishing compound to remove buildup, then buff with a soft cloth to restore clarity.
Electrical Connection Maintenance
Regularly check electrical connections to all lighting components. Loose or corroded connections can cause flickering or complete failure. Clean contacts, remove corrosion, and ensure secure connections.
System-Wide Electrical Inspection
Inspect wiring, connectors, and relays associated with the lighting system for damage or corrosion. Replace any compromised components to ensure reliable operation and prevent electrical issues.

Frequently Asked Questions
The recommended bulb for most Infiniti FX35 models is H11 for low beams and 9005/HB3 for high beams. However, it's essential to check your specific model year and trim level in the owner's manual or with a dealer to confirm the correct bulb type, as specifications can vary between production years and packages.
Yes, LED lights can be used for the Infiniti FX35 side markers. They provide several advantages over factory incandescent bulbs, including:
- Brighter, more modern appearance
- Significantly longer lifespan (30,000+ hours vs. 1,000 hours)
- Lower power consumption
- Faster illumination response time
When selecting LED replacements, ensure you choose the correct bulb size (typically T10/194 for FX35 side markers) and verify compatibility with your vehicle's electrical system to avoid error codes or hyper-flashing issues.
Upgrading the Infiniti FX35 tail lights can be accomplished through several methods:
- Direct bulb replacement: Switch standard incandescent bulbs to LED versions for brighter, faster-responding lights without changing the housing.
- Aftermarket tail light assemblies: Replace the entire tail light unit with custom-designed assemblies offering different styling and lighting technologies.
- LED conversion kits: Install specialized kits designed specifically for the FX35 that maintain the factory housing but upgrade internal components.
- Smoked or clear lens covers: Apply tinted or clear lens covers over existing lights to modify appearance while maintaining functionality.
For best results, follow manufacturer installation instructions and check local regulations regarding tail light modifications, as some alterations may not be street-legal in all jurisdictions.
Upgrading to projector headlights for the Infiniti FX35 offers several significant benefits:
