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

The compatible replacement light bulb part numbers are as follows: Brake # 2357 (or P21W/5W), Rear Turn Signal 1156NA (also 1156A or PY21W), Reverse # 921 (or W16W), Parking Lights # 2357 (or P21/5W) and Side Marker # 168 (or W5W).

The tools needed to access and replace the tail light bulbs include a small plastic pry bar tool, a 10mm socket with a short extension bar and a 1/4" drive ratchet.

Use the plastic pry bar tool to gently pull off the black plastic trim piece located at the inner edge of the tail light housing.

Set the trim panel aside in a safe place.

Once the cover is out of the way, you'll see the two black plastic screws.

Try to pull the tail light housing straight off the rear corner of the SUV.

The housing is still held in place by a metal peg inserted into a plastic grommet and a slot attached to the end of a pop rivet.

You may need to use the plastic pry bar tool to gently pry along the front outer edge of the housing to release the friction fasteners.

I recommend placing a towel on the rear bumper cover to protect the paint and the lens cover from being scratched.

The large black bulb socket contains the brake light bulb.

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

Push a new number 2357 (also known as # P21W/5W) bayonet style light bulb straight into the socket and rotate it 1/4 turn in the clockwise direction to secure it into place.

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

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

Push a new amber colored number 1156NA (also known as # 1156A or PY21W) light bulb straight down into the socket and rotate it 1/4 turn in the clockwise direction to secure it into place.

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

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

Pull the old light bulb straight out of the socket.

If you would like to have brighter rear side marker lights, install some compatible replacement 168 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.

Push the electrical connector and wire harness back on to its mounting bracket.

Line up the metal peg with the white plastic grommet and the plastic "C" shaped slot with the white plastic pop rivet head on the rear corner of the SUV.

Slide the tail light housing back into place.

Re-insert the two black metal screws and spin them in a few turns in the clockwise direction to prevent them from becoming cross threaded.

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

Locate the rectangular shaped access cover.

Insert the plastic pry bar tool into the small notch on the inner edge of the access cover.

Or you can use a large flathead screwdriver.

Once the cover is out of the way, you'll be able to see the two larger parking light sockets and the smaller reverse bulb socket.

Push the bulbs down into the socket and rotate them 1/4 turn in the counterclockwise direction before pulling them straight out.

Push a new number 2357 (or P21/5W) bayonet style light bulb straight into the socket and rotate it 1/4 turn in the clockwise direction to secure it into place.

Pull the old reverse light bulb straight out of the socket and push in a new number 921 (or W16W).

If you would like to have brighter reverse lights, install some compatible replacement 921 LED bulbs.

Re-insert the two tabs on the outer edge in first.

Then gently pop in the inner edge to secure it into place.

To test the new tail light bulbs, have an assistant step on the brake pedal, turn on the parking lights, activate the hazard signals and place the transmission in reverse.

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