  • "A" Designations: When you see a bulb size followed by "A," like 7440A, it indicates that the bulb should be amber in color. This is especially important for turn signals to ensure they are clearly visible.
  • LED CHMSL: The Center High Mount Stop Light (CHMSL) on the 2013 JX35 is an LED unit that is integrated into the assembly. If it fails, you'll need to replace the entire assembly, not just the bulb.
  • Verify with Your Owner's Manual: While this guide is based on the most accurate information available, it's always a good idea to double-check the light bulb sizes listed in your owner's manual. This is the most reliable source for your specific vehicle.
  • Variations: Although unlikely, there might be slight variations depending on specific trim levels or optional packages. Always confirm before purchasing.

Decoding the Bulb Types: A Quick Guide

Let's break down what those bulb designations actually mean. Knowing this will help you understand the options available when you're shopping for replacements.

  • H11: This is a common halogen bulb used in many vehicles for low beams and fog lights. They are known for their good light output and relatively long lifespan.
  • 9005 (HB3): Another halogen bulb, typically used for high beams. They produce a brighter, more focused beam of light than H11 bulbs.
  • 7440/7443: These are wedge-base bulbs commonly used for turn signals, brake lights, and tail lights. The 7443 is a dual-filament bulb, meaning it can perform two functions (like tail light and brake light).
  • 921: A small wedge-base bulb often used for reverse lights.
  • 168/194: These are miniature wedge-base bulbs commonly used for license plate lights, side marker lights, and interior lights. They are relatively low-wattage bulbs.
  • DE3175: A festoon bulb, characterized by its cylindrical shape and contact points at each end. It is frequently used for dome lights.

Halogen, LED, or HID: Choosing the Right Replacement

Now that you know the bulb sizes, you need to decide what type of bulb you want to use as a replacement. Here's a quick rundown of the most common options:

  • Halogen: These are the standard bulbs that came with your 2013 JX35. They are the most affordable option and provide decent light output. However, they have a shorter lifespan and are less energy-efficient than other options.
  • LED (Light Emitting Diode): LED bulbs are becoming increasingly popular due to their long lifespan, energy efficiency, and bright, white light output. They are more expensive than halogen bulbs, but the benefits often outweigh the cost. Important: When replacing halogen bulbs with LEDs, ensure the LED bulb is compatible with your vehicle's electrical system and that it has a built-in resistor to prevent hyper-flashing in turn signals.
  • HID (High-Intensity Discharge): HID bulbs produce a very bright, white light that is similar to daylight. They are more expensive than halogen bulbs and require a ballast to operate. Important: Your 2013 JX35 did not originally come with HID headlights. Converting to HID requires significant modifications and may not be legal in all areas. Improper installation can also damage your vehicle's electrical system.

Recommendation: For most applications, LED replacements offer the best balance of performance, longevity, and energy efficiency. However, always research and choose reputable brands to ensure quality and compatibility.

Step-by-Step Guide to Replacing Common Bulbs

While specific instructions vary depending on the location of the bulb, here's a general guide to replacing common bulbs in your 2013 JX35:

  1. Safety First: Always turn off the vehicle and allow the bulb to cool down before attempting to replace it. Disconnect the negative terminal of the battery for added safety.
  2. Access the Bulb: Depending on the location, you may need to remove a lens cover, access panel, or other components to reach the bulb socket. Consult your owner's manual for specific instructions.
  3. Remove the Old Bulb: Gently twist or pull the old bulb out of the socket. Be careful not to break the bulb.
  4. Install the New Bulb: Insert the new bulb into the socket, making sure it is properly seated.
  5. Test the Bulb: Before reassembling everything, turn on the vehicle and test the new bulb to ensure it is working properly.
  6. Reassemble: Reinstall any lens covers, access panels, or other components that you removed.

Tip: Wear gloves when handling new bulbs to prevent oil from your skin from shortening their lifespan.

Where to Buy Replacement Bulbs

You can purchase replacement bulbs for your 2013 Infiniti JX35 at a variety of locations, including:

  • Auto Parts Stores: Local auto parts stores like AutoZone, Advance Auto Parts, and O'Reilly Auto Parts typically carry a wide selection of bulbs.
  • Online Retailers: Online retailers like Amazon, eBay, and specialized automotive lighting websites offer a vast selection of bulbs at competitive prices.
  • Dealership: Your local Infiniti dealership can also provide replacement bulbs, although they may be more expensive than other options.

Recommendation: Compare prices and read reviews before purchasing bulbs online. Choose reputable brands and vendors to ensure quality and compatibility.

Troubleshooting Common Lighting Problems

Sometimes, simply replacing a bulb doesn't solve the problem. Here are some common lighting issues and potential solutions:

  • Bulb Burns Out Quickly: This could be caused by a loose connection, a faulty voltage regulator, or using a bulb with the wrong wattage.
  • Bulb Doesn't Light Up: Check the fuse for the corresponding circuit. If the fuse is blown, replace it with a new one of the same amperage. Also, check the bulb socket for corrosion or damage.
  • Hyper-Flashing Turn Signals: This is a common issue when replacing halogen turn signal bulbs with LEDs. It indicates that the LED bulb is drawing less current than the original halogen bulb. You can fix this by installing a resistor in the circuit.
  • Dim Headlights: Dim headlights can be caused by oxidized headlight lenses, a weak battery, or a faulty ground connection.
