2024 Honda Pilot Bulb Size Guide: Headlight, Tail, Fog & More

As an ASE-certified master technician, I’ve seen firsthand how automakers are shifting toward fully integrated lighting systems. The 2024 Honda Pilot (part of the 4th generation introduced in 2023) is a prime example of this trend. Honda has equipped most trims with long-lasting LED technology right from the factory. However, there are still a few traditional halogen bulbs lurking in specific locations, especially on lower trim levels like the LX and Sport.

Whether you are looking to replace a burnt-out incandescent bulb, upgrade your interior lighting, or simply need a reference guide for your garage, this comprehensive bulb size chart has you covered.

Quick Reference: 2024 Honda Pilot Bulb Sizes

Below is the bulb size chart for the 2024 Honda Pilot. Note that "Integrated LED" means the bulb cannot be replaced individually; the entire housing or module must be serviced if it fails.

Note: Trim levels such as the Elite and Touring feature full LED lighting throughout, including rear turn signals and interior dome lights. Lower trims use standard halogen bulbs for rear signals, reverse lights, and license plate illumination.

LED vs Halogen Upgrade Considerations

If you own a trim with standard halogen rear turn signals, reverse lights, or interior bulbs, you might be tempted to upgrade to aftermarket LEDs. Here is what you need to know:

• CANBUS Errors and Hyperflashing: Upgrading your halogen rear turn signals (7440NA) to LED will alter the circuit's electrical resistance. Because LEDs draw significantly less power, the Pilot’s computer may think the bulb is burnt out, resulting in a rapid blinking effect known as hyperflashing. To fix this, you will need LED bulbs with built-in CANBUS resistors, or you will need to splice inline load resistors into the wiring harness.
• Color Temperature: If you are upgrading your license plate (194) or reverse lights (7440), aim for a 5000K to 6000K color temperature to match the crisp, cool white look of the factory LED headlights.
• Space Constraints: Make sure aftermarket LED reverse bulbs aren't too long. The tail light housing on the Pilot has specific depth limits, and oversized LEDs may hit the internal reflector.

How to Replace Each Bulb

While most of your exterior forward lighting is permanent LED, you can service the rear and interior bulbs fairly easily:

• Rear Turn Signal & Reverse Lights: Open the liftgate and locate the access panels on the inner trim, or remove the two 8mm/Phillips screws securing the tail light housing to the body. Carefully pull the housing straight back. Twist the bulb socket counterclockwise to remove it, swap the 7440 bulb, and re-install.
• License Plate Lights: These are located above the rear license plate. You can typically push the housing to one side to release the retaining clip, then pull it down to access the 194 bulb socket. Twist counterclockwise to remove.
• Interior Map/Dome Lights: Use a plastic non-marring trim tool to gently pry the clear plastic lenses off the overhead console. Avoid using a metal flathead screwdriver, as the Pilot's overhead plastics scratch easily. Pull the wedge-style 194 bulb or festoon DE3175 out and push the new one in.

Common Lighting Issues for this Generation

Because the 2024 Honda Pilot is so new, widespread lighting failures are incredibly rare. However, based on the architecture of modern Honda SUVs, here are a few things to watch out for:

• Integrated Headlight Failure: The biggest drawback of integrated LED headlights is that if a single diode or the internal driver board fails, you cannot simply swap a $20 bulb. The entire headlight assembly must be replaced, which can run upwards of $1,000 out of warranty.
• Moisture Intrusion: Keep an eye out for condensation inside the headlight or tail light lenses. A small amount of temporary fogging is normal in high humidity, but pooling water indicates a failed factory seal, which should be addressed under your bumper-to-bumper warranty.

If you are dealing with integrated LED failures, complex electrical gremlins, or you simply don't have the time to tackle an upgrade yourself, don't risk damaging your vehicle's wiring. Find a trusted shop on Repairius.
