Replacing the middle brake light (also known as the third brake light or high-mount brake light) on a 2010 Honda Accord is a straightforward process that can be completed in about 30 minutes. This guide will walk you through the steps to replace the bulb or the entire light assembly, depending on your needs.
Tools and Materials Needed
To replace the middle brake light on your 2010 Honda Accord, you’ll need the following tools and materials:
- Phillips head screwdriver
- Flathead screwdriver
- Replacement bulb (7440 type) or new brake light assembly
- Clean cloth or gloves
- Trim removal tool (optional)
Having these items on hand before you start will make the process smoother and more efficient.
Locating the Middle Brake Light
The middle brake light on a 2010 Honda Accord is located at the base of the rear windshield, inside the vehicle. To access it:
- Open the trunk of your Honda Accord.
- Look up towards the rear windshield from inside the trunk.
- You’ll see the brake light assembly mounted on the rear deck, just below the windshield.
This central position allows the light to be visible to drivers behind you, even when your regular brake lights might be obscured.
Removing the Trunk Liner
To access the middle brake light, you’ll need to remove part of the trunk liner:
- Locate the plastic fasteners holding the trunk liner in place near the brake light.
- Use a flathead screwdriver or trim removal tool to carefully pry out these fasteners.
- Gently pull back the trunk liner to expose the back of the brake light assembly.
Be careful not to damage the liner or the fasteners as you remove them. Keep the fasteners in a safe place for reinstallation later.
Accessing the Brake Light Assembly
Once you’ve removed the trunk liner, you’ll be able to see the back of the brake light assembly:
- Look for the wiring harness connected to the light assembly.
- You may see one or two screws holding the assembly in place.
- If there are screws, remove them with a Phillips head screwdriver.
At this point, you should be able to easily access the bulb or the entire light assembly, depending on what needs to be replaced.
Replacing the Bulb
If only the bulb needs replacement:
- Locate the bulb socket at the back of the assembly.
- Turn the socket counterclockwise to remove it from the housing.
- Pull the old bulb straight out of the socket.
- Insert the new 7440 type bulb into the socket, making sure not to touch the glass part with your bare hands.
- Reinsert the socket into the housing and turn clockwise to secure it.
Always handle the new bulb with a clean cloth or gloves to prevent oils from your skin from damaging the bulb.
Replacing the Entire Light Assembly
If you need to replace the entire light assembly:
- Disconnect the wiring harness from the old assembly.
- Remove any remaining screws or fasteners holding the assembly in place.
- Carefully pull the old assembly out through the opening in the trunk.
- Insert the new assembly into the same position.
- Secure it with the screws or fasteners you removed earlier.
- Reconnect the wiring harness to the new assembly.
Make sure the new assembly is properly aligned and securely fastened before moving on to the next step.
Reinstalling the Trunk Liner
After replacing the bulb or assembly, it’s time to put everything back together:
- Carefully reposition the trunk liner back into place.
- Line up the holes for the plastic fasteners.
- Push the fasteners back into their holes until they click into place.
- Double-check that the liner is secure and properly aligned.
Ensure all fasteners are properly seated to prevent rattling or water intrusion.
Testing the New Light
Before considering the job complete, it’s crucial to test the new middle brake light:
- Close the trunk and enter the vehicle.
- Turn on the ignition (you don’t need to start the engine).
- Press the brake pedal.
- Have someone confirm that the middle brake light is functioning correctly.
If the light doesn’t work, double-check your connections and ensure the bulb is properly seated in its socket.
Common Issues and Troubleshooting
Sometimes, you might encounter issues during or after the replacement process. Here are some common problems and solutions:
Light doesn’t work after replacement:
- Check if the bulb is properly seated in the socket.
- Ensure the wiring harness is securely connected.
- Test the bulb in another socket to confirm it’s not defective.
Water leakage after replacement:
- Verify that the light assembly is properly sealed.
- Check for any gaps or misalignment in the installation.
Difficulty removing the old assembly:
- Look for hidden screws or clips that might be securing it.
- Consult your vehicle’s manual for specific removal instructions.
Rattling noise after reinstallation:
- Ensure all screws and fasteners are tight.
- Check that the trunk liner is properly secured.
If you encounter persistent issues, it may be best to consult a professional mechanic or your Honda dealer.
Maintenance Tips
To keep your middle brake light functioning properly:
- Regularly check all brake lights as part of your routine vehicle maintenance.
- Clean the light cover periodically to ensure maximum visibility.
- If you notice any dimming or flickering, replace the bulb promptly.
- Check for any signs of moisture inside the light assembly, which could indicate a seal problem.
Proper maintenance can extend the life of your brake lights and ensure your vehicle remains safe on the road.
