2019 Sorento Tailgate
License Plate Bulb Housing
Loosen Counterclockwise

This automotive maintenance tutorial was specifically written to assist owners of the third generation (2016, 2017, 2018, 2019 and 2020) Kia Sorento SUV in changing a burnt out license plate light bulb in the tailgate.

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

The compatible replacement festoon style light bulb part number is 6418 (also known as C5W or 12844) which are available from various manufacturers such as Sylvania, Philips, GE, Eiko, Bosch and PIAA.

If you would like to have brighter license plate lights that will last a lot longer before burning out, install some 6418 LED bulbs. (The correct bulb length is 36mm.)

The tools needed to access and replace the bulbs include a Phillips head screwdriver and a small flat head screwdriver or a plastic pry bar tool.

Remove the two screws that secure the translucent plastic lens cover to the light housing by turning them in the counterclockwise direction with the Phillips head screwdriver.

Make sure the new light bulb is securely attached in between the two metal electrical contacts.

Line up the lens cover with the light housing.

Lens Cover Installed
Spin In Phillips Screw
Tighten Clockwise
Push the lens cover into place and hold it with one hand.

Use your other hand to spin in the two screws a few turns in the clockwise direction to make sure they don't become cross threaded.

Replace 2nd Screw
Lens Cover Secured
Test New Light Bulb
Tighten the two screws by turning them in the clockwise direction with the Phillips head screwdriver.

Try to avoid over tightening the screws to prevent from cracking the plastic lens cover.

To test the new license plate light bulbs, turn on the parking lights or the headlights. You could also press the "Unlock" button on the key fob to re-activate the exterior lights.

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