In a 2007 Honda Fit, brake lights can be the center high‑mount brake light (CHMSL) or the left and right rear taillights. Replacing the bulb is a straightforward DIY task that involves accessing the bulbs from inside the rear hatch, removing the old bulb, and installing a fresh bulb of the correct type. Always switch off the ignition and test the lights after replacement.
What you’ll need
Gather the tools and replacement bulbs before you begin. The Fit uses specific bulb types for the center light and the taillights, so having the correct replacements on hand will save time.
- Replacement bulbs (check the old bulb or the owner’s manual for the exact type)
- Flat-head screwdriver or panel removal tool
- Gloves or clean cloth to handle bulbs (to avoid oils on the glass)
- Torx or Phillips screwdriver (if required by your trim)
- Flashlight or work light for better visibility
Having the right tools and bulbs on hand makes the job faster and reduces the risk of damaging trim or the light housing.
Replacing the Center High-Mount Brake Light (CHMSL)
The CHMSL sits at the top of the rear hatch. Accessing it usually requires removing the interior trim cover inside the hatch and disconnecting the bulb socket from the housing.
- Open the hatch and remove the interior trim panel around the CHMSL to gain access to the light assembly.
- Unclip or unscrew the CHMSL housing if needed, and disconnect the electrical connector.
- Push or twist the bulb socket counterclockwise to remove it from the housing, then pull the old bulb straight out.
- Install the new bulb, reinsert the socket, and reconnect the connector.
- Reattach the CHMSL housing and the hatch trim. Test the brake light by pressing the brake pedal.
If the CHMSL remains dark after replacement, the issue could be a blown fuse or a faulty CHMSL module; consult the owner's manual or a technician for further diagnosis.
Replacing the Left and Right Tail/Brake Lights
These lights are accessed from inside the trunk by removing the side trim and the light housing to reach the bulb socket.
- Fold down or remove the trunk floor cover and peel back the side panel on the side with the affected light.
- Remove the two screws or fasteners securing the taillight housing from the inside; gently pull the assembly away to expose the bulb socket.
- Unplug the electrical connector and twist the bulb socket counterclockwise to release it from the housing.
- Pull out the old bulb and replace it with the correct replacement bulb.
- Reconnect the socket, reseat the taillight housing, and reattach the side panel and carpet trim.
- Close the trunk and press the brake pedal to verify the new brake light lights up.
If the new bulb lights but one side remains out, verify the other light or check for a blown fuse, a wiring issue, or a loose connector in the circuit.
Tips and troubleshooting
Always handle bulbs with gloves or a clean cloth to avoid oils on the glass, which can shorten bulb life. If you’re unsure which bulb type to buy, remove the existing bulb and check its markings or consult the owner’s manual and Honda’s parts catalog. Some trims require slightly different bulbs for the CHMSL versus the taillights.
Test, reassemble, and finalize
After replacing any bulb, test the brake lights with the trunk closed and the hatch secured to ensure proper operation. If you notice flickering, dimming, or no illumination, re-check bulb seating and connectors. If you encounter stubborn trim panels or missing fasteners, consider consulting a professional to avoid damage.
Summary
Changing the brake light on a 2007 Honda Fit involves identifying which light is out, accessing the bulb through the rear hatch interior, replacing with the correct bulb type, and reassembling before testing. The process varies slightly between the center CHMSL and the left/right taillights, but the core steps—gain access, remove the old bulb, install the replacement, and verify—remain the same. Regular checks can help prevent a burnt-out brake light from going unnoticed.
