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

The compatible replacement light bulb part numbers are as follows: Brake # 2357, Rear Turn Signal # 1156A (or 1156NA), Reverse # 921 (or W16W), Parking Light # 2825 (or W5W) and Rear Side Marker # 2825 (or W5W).

If you would like to have brighter tail lights, choose 2357 LED, 1156A LED, 921 LED and 2825 LED light bulbs.

The tools needed to complete this procedure include a standard Phillips head screwdriver and a plastic pry bar tool.

The first two steps are to open the tailgate door for the cargo area and then move to the tail light housing that contains the burnt out bulb.

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

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

The tail light housing is still held in place to the rear of the vehicle by three metal pegs or "spikes" that are inserted into plastic grommets.

So you may have difficulty just pulling it off with out first loosening these friction fasteners.

Gently pry to loosen the friction fasteners.

Do not use excessive force to prevent from cracking the plastic lens cover.

You may need to re-insert the tool in several locations to fully release the three friction fasteners.

If you are in a cold climate, I recommend performing this procedure in a warm garage and use a space heater to warm up the tail light housing to help reduce the risk of cracking the plastic housing.

Push in the release tab on the black plastic electrical connector before sliding it straight out of its socket.

Set the tail light housing down on a soft surface such as on the cargo area's carpet to prevent from scratching the plastic lens cover.

Rotate the large grey plastic bulb 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 of the socket.

If you would like to have brighter brake lights, install some compatible replacement 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.

The reverse light bulb socket is located just above the brake light bulb.

Rotate the smaller grey / white bulb socket 1/4 turn in the counterclockwise direction before pulling it straight out.

Push a new number 921 miniature wedge base light bulb straight into the socket.

Or install a brighter 921 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.

The rear turn signal light bulb is located above the reverse bulb and closer to the top 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.

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

For brighter rear turn signals, install some compatible replacement 1156A LED bulbs.

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

The procedure for replacing either of them is the same.

Rotate the small 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 parking and rear side marker lights, install some 2825 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.

Hold the tail light housing near the rear corner of the vehicle and push the electrical connector back into its socket.

The power plug should "click" securely into place.

Carefully slide the tail light housing back into place.

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

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

Tip - If you installed any LED bulbs and they don't work, try removing them from the socket, rotating them 180 degrees and pushing them 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.

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