How to Fix Honda Fit Brake Light Failure - Useful Tips

By Nick Marchenko, PhD

Having functioning brake lights on your Honda Fit is crucial for safety and legal compliance. If you've encountered an issue where one or more of your brake lights have stopped working, don't fret. This guide consolidates advice from several discussions, providing a step-by-step approach to diagnose and fix common brake light problems in a Honda Fit. Let's delve into the troubleshooting process, ensuring you're equipped to tackle this repair with confidence.

Preliminary Checks

Before diving into more complex solutions, perform these simple checks:

• Check All Brake Lights: Confirm which brake lights are not working. Honda Fits are equipped with multiple brake lights, including two main lights on the vehicle's rear and a third brake light, often located on or near the rear windshield.
• Test the Brake Lights in Different Conditions: Verify if the brake lights work under various conditions, such as when locking/unlocking the car or with the headlights on. This can help narrow down the issue.

Common Causes and Fixes

1. Burnt-Out Bulb

One of the most common reasons for a brake light failure is a burnt-out bulb.

How to Replace a Brake Light Bulb:

• Identify the Affected Bulb: Determine which brake light is not working. If it's one of the main brake lights, it might be due to a dual filament bulb where only one filament has burnt out.
• Access the Bulb: Open the trunk or hatch to access the back of the brake light assembly.
• Replace the Bulb: Remove the faulty bulb by twisting and pulling it out. Insert a new bulb of the correct type and size. Dual filament bulbs are often used for brake lights, so ensure you have the correct replacement.

If you are planning to replace a bulb - make sure that you are choosing the proper one. The wrong bulb may not function properly on your car and even lead to some serious consequences. Check our bulb size chart to make fuse that you are buying the bulb that matches your Honda Fit electrical system:

• 2012;
• 2011;
• 2010;
• 2009;
• 2008;

2. Fuse Issue

If all brake lights stopped working simultaneously, the problem might be related to a fuse.

How to Check and Replace a Fuse:

• Locate the Fuse Box: Check the owner's manual for the location of the fuse box. Honda Fits typically have one under the dashboard and another under the hood.
• Identify the Brake Light Fuse: Look for a fuse labeled for the brake lights. Refer to the fuse diagram on the fuse box cover or the owner's manual.
• Inspect and Replace: Remove the fuse using a fuse puller and inspect it. If the metal strip inside is broken, replace the fuse with one of the same amperage.

3. Faulty Brake Light Switch

A defective brake light switch can also cause brake lights to stop working. This switch activates the brake lights when the brake pedal is pressed.

How to Replace the Brake Light Switch:

• Locate the Switch: Find the brake light switch above the brake pedal.
• Test the Switch: Disconnect the electrical connector and use a multimeter to check for continuity. There should be continuity when the brake pedal is pressed and no continuity when released.
• Replace the Switch: If the switch is faulty, unscrew it and replace it with a new one. Ensure the new switch is properly adjusted so the brake lights activate when the pedal is pressed.

4. Wiring or Connector Issues

If the above steps don't resolve the issue, inspect the wiring and connectors for damage or loose connections. Ensure the wiring to the brake light switch and the brake lights themselves is intact and securely connected.

Final Checks

After attempting the repairs, perform the following:

• Test the Brake Lights: Have someone press the brake pedal while you check the lights from the rear of the vehicle.
• Ensure Safety: Make sure all lights and assemblies are securely in place to avoid any safety hazards.

Conclusion

Repairing brake light issues on a Honda Fit can range from simple bulb replacement to more complex electrical troubleshooting. By following this guide, you'll be equipped to address the most common brake light problems. Remember, regular maintenance and checks can prevent such issues from occurring in the first place. Safe driving begins with ensuring that all your vehicle's lights are fully operational.
