2024 Honda Accord Bulb Sizes: Headlight, Tail, Fog Light Guide

The 2024 Honda Accord (11th generation) continues Honda’s trend of integrating advanced lighting technology across its lineup. As an ASE-certified master technician, I’ve seen firsthand how the shift toward factory LED assemblies has changed routine maintenance. If you own a 2024 Accord, much of your exterior lighting is already LED, meaning traditional bulb replacements are less common than in older generations. However, certain trims and specific lighting locations still rely on replaceable halogen bulbs.

Here is everything you need to know about your 2024 Honda Accord’s lighting system, including bulb sizes and replacement tips.

Quick reference

Below is the bulb size chart for the 2024 Honda Accord. Keep in mind that higher trims (like the Touring Hybrid) often feature full LED systems, whereas base trims (LX, EX) may use halogen bulbs in the rear and interior.

Note: The 2024 Accord does not come with factory fog lights on any trim level.

LED vs halogen upgrade considerations

Because the 2024 Accord comes standard with built-in LED low and high beams, you will not need to upgrade your headlights. The entire headlight housing is a sealed LED unit.

However, many owners choose to upgrade their remaining incandescent halogen bulbs—such as the rear turn signals, reverse lights, and interior dome lights—to aftermarket LEDs for a cleaner, more modern look.

If you are upgrading the rear turn signals (7440), be aware of "hyper-flashing." This rapid blinking occurs because LEDs draw much less power than halogens, tricking the car's CANBUS system into thinking the bulb is burned out. To prevent this, you will need either an LED bulb with a built-in load resistor (often marketed as "CANBUS error-free") or to install external inline load resistors.

For interior and license plate lights (size 194), simply swapping in high-quality LED replacements is usually plug-and-play without triggering any dashboard errors.

How to replace each bulb

While sealed LED units require a complete housing replacement if they fail, the remaining traditional bulbs are relatively easy to service:

• Rear Turn Signals & Reverse Lights: Open the trunk and pull back the interior fabric liner behind the tail light housing. You will see the plastic bulb sockets. Twist them counterclockwise to remove them, pull the old halogen bulb straight out, and push the new one in.
• License Plate Lights: These can be accessed from the outside. Use a plastic trim removal tool to gently pry the lens assembly out of the trunk lid. Twist the socket to pull out the 194 bulb.
• Dome and Map Lights: Use a thin, non-marring plastic pry tool to pop the clear plastic lenses off the overhead console. Be extremely gentle to avoid cracking the lens or snapping the retaining clips. Swap the bulb and snap the lens back into place.
• Headlights / Brake Lights: Since these are integrated LED assemblies, if a diode burns out, the entire housing must be replaced. Fortunately, these are designed to last the lifetime of the vehicle and are covered under Honda's bumper-to-bumper warranty for new vehicles.

Common lighting issues for this generation

The 11th-generation Accord is still quite new, so widespread lighting failures are extremely rare. The most common issue owners face is condensation inside the sealed LED headlight or tail light housings. A small amount of fogging after a heavy rain or car wash is normal due to temperature changes and the housings' passive vents. However, if water droplets pool at the bottom of the lens, the seal has failed, and the assembly should be replaced under warranty.

Additionally, upgrading the rear turn signals to cheap aftermarket LEDs without proper resistors can cause electrical gremlins or fast-blinking indicators. Always invest in quality LED replacements to match the reliability of your Honda.
