The compatible replacement miniature wedge base light bulb part number is W3W (also known as part # 2821) which are available from various manufacturers such as Sylvania, GE, Eiko, Bosch and PIAA.

If you would like to have brighter front side marker lights, install some 2821 LED bulbs.

The tools needed to access the socket and replace the bulb include a Phillips head screwdriver and possibly also a plastic pry bar tool.

(If your Civic is equipped with fog lights, the procedure for accessing and replacing those bulbs is very similar to the steps shown on this page.)

The first step is to turn the steering wheel all the way in the opposite direction of the burnt out front side marker light bulb.

Moving the tire out of the way will help create more working room in the wheel well.

Remove the three screws by turning them in the counterclockwise direction with a Phillips head screwdriver.

Set the three screws aside in a safe place.

You may need to use a plastic pry bar tool or a flat head screwdriver to separate the wheel well liner from the front quarter panel and front bumper cover.

Reach in behind the orange plastic side marker light housing.

Rotate the small grey plastic bulb socket 1/4 turn in the counterclockwise direction before pulling it straight out of the housing.

If you have trouble removing a stuck or stubborn bulb that may be a bit rusty, try carefully wiggling it back and forth before pulling it straight out.

The OEM (original equipment manufacturer) bulb in this 2016 Civic was a W3W which is the same as the Sylvania 2821 (3 watts 12 volts).

If you would like to have brighter front side marker lights, install some compatible 2821 LED bulbs.

Push the new bulb straight into the socket.

Re-insert the bulb socket into the housing and rotate it 1/4 turn in the clockwise direction to secure it into place.

If you installed an LED bulb, I recommend testing it before replacing the wheel well liner.

If the LED bulb doesn't work, try removing it from the socket, rotating it 180 degrees and pushing 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.

Replace the three screws by turning them in the clockwise direction with a Phillips head screwdriver.

To test the new side marker light bulb, turn on the parking lights or the headlights.

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