2018 Sportage Tail Lights
Open Tailgate Door
Pry Off Trim Panel
This automotive maintenance tutorial was specifically written to assist owners of the fourth generation (2017, 2018, 2019 and probably also the refreshed 2020, 2021 and 2022) Kia Sportage SUV in changing a burnt out brake or rear side marker bulb located in the tail light housings.

Owners of other Kia, Hyundai and Genesis vehicles such as the Niro, Optima, Soul, Forte, Rio, Stinger, Cadenza, K900, Sorento, Telluride, Sedona, Kona, Santa Fe, Tucson, Elantra, Sonata, Accent, Rondo, Carens, Veloster, Ioniq, Nexo, Palisade, G70, G80 and G90 may also find these DIY instructions to be helpful.

The compatible replacement light bulbs with their part numbers are as follows: Brake # 2357 and Rear Side Marker # 2825 (also known as W5W).

If you would like to have brighter tail lights that will last longer, install some 2357 LED and 2825 LED bulbs.

The tools needed to remove the tail light housing and access the bulb sockets include a small flathead screwdriver or a plastic pry bar tool and a Phillips head screwdriver.

The first two steps are to open the tailgate door for the cargo area and then move to the side of the SUV with the burnt out tail light bulb.


Pull Off Trim Cover
Two Screws Exposed
Loosen Counterclockwise
Locate the two small notches on the outer edge of the black plastic trim cover.

Insert the blade of the flathead screwdriver or the plastic pry bar tool into one of the two notches.

Gently pry off the black plastic trim panel and set it aside in a safe place.

Once the cover is out of the way, you'll be able to see the two black metal screws that secure the tail light housing to the rear corner of the SUV.

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

Two Screws Removed
Pull Off Tail Light Housing
Slide Assembly Off Car
Set the two screws aside in a safe place.

Carefully pull the tail light housing straight off the rear of the SUV.

The housing is still held in place by two metal pegs on the back side that are inserted into plastic grommets and also a plastic slot attached to the button head of a plastic pop rivet.

If you have trouble removing the tail light housing, try gently wiggling the housing up and down or left and right while pulling it straight off.

Two Pegs & Slot
Push Release Tab
Turn over the tail light housing to access the bulb sockets.

You may want to place a towel on the rear bumper to protect the tail light lens cover and painted bumper from being scratched.

I chose to disconnect the electrical connector for the entire tail light housing and set the housing down in the cargo area.

To disconnect the power plug, push in the release tab and slide the connector straight out of its slot.

1/4 Turn Counterclockwise
Rear Side Marker Socket
Pull Out Old Light Bulb
The smaller grey bulb socket contains the rear side marker light bulb.

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

Carefully pull the old light bulb straight out of the socket.

If you have trouble removing a stuck or stubborn old bulb that might be rusted in place, try gently wiggling it back and forth while pulling it straight out.


Old Side Marker Bulb
Push In New Light Bulb
1/4 Turn Clockwise - Lock
Push a new number 2825 light bulb straight into the socket.

If you would like to have a brighter rear side marker light that will also last a lot longer before burning out, install a compatible replacement 2825 LED bulb.

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

1/4 Turn Counterclockwise
Brake Light Bulb Socket
Push Down 1/4 Turn CC
The larger dark grey bulb socket contains the brake (or "stop") light bulb.

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

Push the old bulb down into the socket and rotate it 1/4 turn in the counterclockwise direction before pulling it straight out.

The original OEM light bulb was marked as part number KHA12V28/8W.

Install New Light Bulb
1/4 Turn Clockwise - Lock
Push In Power Plug
Push a new number 2357 light bulb down into the socket and rotate it 1/4 turn in the clockwise direction to secure it into place.

If you would like to have brighter brake lights, install some compatible 2357 LED bulbs.

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 disconnected the electrical connector for the tail light housing, push it back into its socket.

Line Up Pegs & Slot
Slide On Tail Light Housing
Tighten Screws Clockwise
Line up the two metal pegs (or "spikes") and the plastic slot on the back side of the tail light housing with the corresponding white plastic grommets and the white plastic pop rivet button head on the rear quarter panel of the SUV.

Slide the tail light housing back into place.

Replace Lower Screw
Push On Trim Piece
Test New Tail Light Bulbs
Replace the two screws by turning them in the clockwise direction with a Phillips head screwdriver until they are snug.

Try to avoid over tightening the two screws to prevent from cracking the plastic inner edge of the tail light housing.

Line up the black plastic trim cover and snap it back into place to secure the retaining clips.

To test the new tail light bulbs, have an assistant step on the brake pedal and turn on the parking lights.
