1997-2000 Infiniti QX4 Front Turn Signal: A Guide to the Bumper-Mounted Lamp
This guide covers the often-misidentified front bumper-mounted turn signal and parking light assembly for the 1997-2000 Infiniti QX4, including common issues and replacement tips.
- This part is the bumper-mounted turn signal/parking lamp, NOT the main headlight assembly.
- The most critical inspection point on a used unit is the integrity of the plastic mounting tabs, which become brittle with age.
- The turn signal uses a common 1156 incandescent bulb; upgrading to LEDs requires a resistor or a new flasher relay to prevent hyperflashing.
- New OEM parts (LH: 26135-1W326, RH: 26130-1W326) are becoming rare and may be discontinued, making used OEM or aftermarket the most likely options.
A Critical Clarification: This is NOT the Headlight Assembly
Important: The part covered in this guide is the front turn signal and parking lamp assembly, which is mounted in the front bumper. It is frequently confused with the main headlight assembly or the corner marker light. The OEM part numbers for this assembly are 26135-1W326 (Left/Driver Side) and 26130-1W326 (Right/Passenger Side). Always verify the part's location on your vehicle before purchasing.
Symptoms of a Failing Turn Signal Assembly
Failure of this assembly can present in several ways, ranging from simple bulb issues to physical damage to the housing itself.
- Turn Signal or Parking Light is Out: The most common issue is a burnt-out bulb. This assembly uses a standard 1156-type bulb for the turn signal function.
- Hyperflashing: If your turn signal blinks much faster than usual, it's called hyperflashing. This is the vehicle's way of telling you a bulb is burnt out. It can also occur if you install LED bulbs without the necessary supporting hardware.
- Moisture or Condensation Inside Lens: If you see water droplets or fogging inside the lens, the seal between the lens and the housing has failed. This can cause chronic bulb failure and corrosion in the electrical socket.
- Cracked or Hazy Lens: Over 25+ years, the plastic lens can become yellow, hazy, or brittle from UV exposure and weather. Cracks from impacts with road debris are also common, which will inevitably lead to moisture intrusion.
- Visible Physical Damage: Because they are mounted low in the bumper, these lights are often the first casualties in a minor front-end collision or parking lot bump.
Known Issues, Recalls, and Technical Service Bulletins (TSBs)
While there are no specific recalls or TSBs for the turn signal assemblies on the 1997-2000 QX4, the vehicle itself has been subject to several major safety campaigns you should be aware of.
Vehicle-Specific Recalls (Not Part-Specific)
- Strut Housing Corrosion: A major recall was issued for QX4s sold in cold-weather states due to severe corrosion of the front strut tower housing. Road salt could collect and cause the structure to rust, potentially leading to a loss of steering control.
- Takata Airbag Inflators: Like millions of other vehicles, the QX4 was included in the massive Takata airbag recall. Faulty inflators could rupture during deployment, causing serious injury. You can check if your specific vehicle is affected by entering your VIN on the NHTSA website.
Pro Tip: The 1997-2000 Infiniti QX4 is mechanically similar to the Nissan Pathfinder of the same era (R50 platform), but body panels and lighting are generally not interchangeable without significant modification. Do not assume a Pathfinder turn signal will fit your QX4.
Buying a Used 1997-2000 QX4 Turn Signal Assembly
Given that new OEM assemblies are becoming difficult to find and may be discontinued, a quality used OEM part is often the best choice. Aftermarket options exist, but fit and finish can be inconsistent. Here’s what to look for when buying used.
Inspection Checklist:
- Check All Mounting Tabs: This is the most critical inspection point. After decades of heat cycles and vibration, the plastic mounting tabs become extremely brittle. Ask for clear photos of every tab to ensure none are cracked or broken. A light with a broken tab will not sit securely in the bumper.
- Inspect the Lens Carefully: Look for hairline cracks, especially around the edges. Check for hazing or yellowing from UV damage, which reduces light output.
- Look for Signs of Moisture: Check for a "water line" or mineral deposits on the inside of the lens or on the chrome reflector. This indicates the seal has failed and the light has had water inside it.
- Examine the Bulb Socket and Connector: The electrical socket where the bulb twists in should be clean and free of any green or white corrosion. The external electrical connector should also be inspected for damage or corrosion.
- Verify the Part Number: Ensure you are buying the correct side. The Left (Driver) side is 26135-1W326 and the Right (Passenger) side is 26130-1W326.

Frequently Asked Questions (FAQ)
Is this the same as the fog light?
No. The turn signal assembly is a separate unit from the fog light, though they are both located in the front bumper. The fog light for the right side is part number 26150-1W325. Be sure to order the correct lamp for your needs.
What bulbs do I need for this assembly?
The front turn signal function uses one 1156-type incandescent bulb. The parking light function uses a different bulb, typically a small wedge-style bulb like a 168 or 194. Always check the existing bulb or your owner's manual to confirm before purchasing replacements.
Why is my turn signal blinking really fast after I installed an LED bulb?
This is called "hyperflashing." The vehicle's flasher relay is designed to detect the electrical resistance of a standard incandescent bulb. Since LEDs draw much less power, the relay thinks the bulb is burnt out and flashes quickly as a warning. To fix this, you must either wire in a load resistor for each LED bulb or replace the stock flasher relay with an electronic LED-compatible flasher, such as a CF15 model.
Do I need to remove the bumper to replace this light?
In most cases, you do not need to remove the entire front bumper. You can typically gain access to the back of the turn signal assembly by removing a few screws or clips from the plastic fender liner inside the wheel well and pulling it back.
