2016 Civic Trunk Light
Notch - Right Side
Insert Screwdriver
This automotive maintenance tutorial was specifically written to assist owners of the tenth generation 2016, 2017, 2018 and 2019 Honda Civic sedan in changing a burnt cargo area light bulb located in the trunk. The procedure might be similar for the coupe or hatchback models.

Owners of other Honda or Acura vehicles such as the Accord, Insight, Clarity, Fit, HR-V, CR-V, Pilot, Passport, Odyssey, Ridgeline, ILX, MDX, RDX, NSX, RLX and TLX may also find these DIY instructions to be helpful.

The compatible replacement miniature wedge base light bulb part number is 168 from manufacturers such as Sylvania, GE, Eiko and PIAA.

If you would like to have a brighter cargo area light that will also last a lot longer, install a 168 LED bulb.

The only tool needed to remove the light housing and replace the bulb is a small plastic pry bar tool or a flathead screwdriver.

The first two steps are to open the trunk lid and then locate the light housing in the "ceiling" of the cargo area situated in between the two rear deck speakers.

There is a small notch on the right (passenger) side of the light housing.


Pry Out Light Housing
Pushing Out Housing
Light Housing Removed
Insert the blade of your screwdriver or plastic pry bar tool into the small notch.

Gently pry out the right side of the light housing to release the retaining clip.

I also found it helpful to insert my finger into the opening just to the right of the light housing and push it down out of its mounting location.

Gently pull the light housing out of the ceiling of the trunk.

Push In Release Tab
Power Plug Detached
Pull Out Old Light Bulb
Push in the release tab on the white plastic electrical connector before sliding it straight out of its socket.

If the old light bulb was recently turned on, allow it to cool off for a few minutes. The old bulb might still be hot enough to burn your fingers.

Gently pull the old bulb straight out of the socket.

If you have trouble removing the old bulb, try gently pushing it out of the socket at the base of the bulb with the screwdriver or pry bar tool.

Old Light Bulb Removed
12V5W Bulb
Empty Bulb Socket
Try to avoid bending or damaging the metal electrical contacts.

The OEM (original equipment manufacturer) bulb was marked as a "12V5W" which is the same voltage and wattage as the common 168 automotive bulb.

Push In New Light Bulb
Push In Electrical Connector
Re-Insert Wires First
Push a new number 168 light bulb straight into the socket.

If you would like to have a brighter cargo area light, install a compatible replacement 168 LED bulb.

Push the power plug straight into the socket on the light housing.

You should feel or hear the connector "click" securely into place.

The new bulb should have lit up as soon as you pushed into the electrical connector.

Tip - If you installed an LED bulb and it doesn't work, try removing it from the socket, rotate it 180 degrees and push it back into the socket. Some LED bulbs are polarized and will only work when the "+" positive and "-" negative electrical contacts are in the correct orientation.

Re-insert the wires on the left side of the housing back into the opening in the ceiling of the trunk first.

Replace Light Housing
Pop In Retaining Clip
Test New Trunk Light Bulb
Then gently snap in the plastic retaining clip on the right side of the light housing.

Be sure to record the bulb change in your car's service records.
