2020 Honda Pilot Bulb Sizes: Complete Replacement Guide

As an ASE-certified master technician, I regularly service the Honda Pilot. The 2020 Honda Pilot (part of the third-generation refresh) features a mix of traditional halogen bulbs and modern LED technology. Honda made LED low-beam headlights standard across all trims for this model year, but depending on whether you drive an LX, EX, Touring, or Elite, your high beams and fog lights might differ.

Whether you are looking to upgrade your halogen high beams to LEDs or simply need to replace a burnt-out turn signal, this guide provides all the bulb sizes and replacement tips you need.

Quick reference

Here is the complete bulb size chart for the 2020 Honda Pilot. Note: "Assembly" means the LED is integrated into the housing and cannot be replaced as a standalone bulb.

LED vs halogen upgrade considerations

Many 2020 Honda Pilot owners with LX, EX, or EX-L trims choose to upgrade their halogen high beams (9005) and reverse lights (921) to LEDs to match the factory LED low beams and DRLs. If you decide to go this route, keep the following in mind:

• CANBUS Errors and Flickering: The 2020 Pilot's electrical system is relatively forgiving, but cheap LED bulbs can still cause hyper-flashing (especially in turn signals) or dashboard error messages. Always look for "CANBUS error-free" LED bulbs or install in-line load resistors for your turn signals.
• Clocking the Bulbs: When installing 9005 LED high beams, ensure the LED chips are facing the 3 o'clock and 9 o'clock positions. This mimics the halogen filament and provides the correct beam pattern in the reflector housing.
• Space Constraints: Some high-output LED bulbs have large cooling fans or heat sinks on the back. Check the clearance behind your headlight assembly to ensure the dust cap can be reinstalled properly.

How to replace each bulb

Here are a few quick technician tips for accessing and replacing the most common bulbs on your 2020 Honda Pilot:

• High Beam Headlights (9005): These are easily accessible from under the hood. On the passenger side, you may need to unclip the windshield washer fluid neck for better access. Simply twist the bulb counterclockwise to remove it.
• Front Turn Signals (7443A): You can reach these from inside the engine bay, but if you have large hands, accessing them through the front wheel well liner (by turning the steering wheel and removing a few plastic clips) is often easier.
• Fog Lights (H8): The easiest way to access the fog lights is from underneath the vehicle or through the front wheel well liner. Remove the plastic clips holding the splash shield, pull the plastic back, and twist the bulb out.
• Rear Turn Signals (7440A) and Reverse Lights (921): Open the liftgate and remove the plastic trim covers behind the taillight assembly. You'll need to remove a couple of 8mm bolts to pull the taillight housing away from the body. Once the housing is loose, the bulbs twist right out.
• Interior Dome/Map Lights: Use a plastic trim removal tool to gently pry the clear plastic lenses off. Never use a metal flathead screwdriver, as it will easily scratch the plastic and tear the headliner.

Common lighting issues for this generation

The refreshed third-generation Honda Pilot is a highly reliable vehicle, but there are a few lighting quirks to be aware of:

• LED Assembly Failure: Because the low beams, DRLs, brake lights, and tail lights are integrated LED assemblies, a burnt-out LED means replacing the entire housing. While LEDs are designed to last the lifetime of the vehicle, electrical surges or physical damage can cause premature failure, resulting in an expensive replacement.
• Moisture in Taillights: Some owners have reported condensation building up inside the rear taillight assemblies. If the moisture doesn't evaporate after a few hours in the sun, the seal may be compromised, and the housing will need to be resealed or replaced.
• Rodent Damage: The soy-based wiring insulation used in modern Hondas can attract rodents. If multiple lights on one side of your Pilot suddenly stop working, check the wiring harnesses under the hood for chew marks.
