2019 Sorento Dome Light
Two Small Slots - Front
Insert Screwdriver

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 dome light bulb in the overhead housing attached to the headliner above the second row of passenger seats.

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 DE3175 which is available from various manufacturers such as Sylvania, GE, Bosch, Philips, Eiko and PIAA.

If you would like to have a brighter dome light, install a DE3175 LED bulb.

The only tool needed to access and replace the light bulb is a small plastic pry bar tool or a flat head screwdriver.

To prevent from scratching the plastic surfaces, I recommend either using a plastic trim panel removal tool or cover the tip of your screwdriver with a thin micro fiber cloth.

Locate the two small notches on the front edge of the lens cover (located closer to the front of the vehicle).

Carefully insert the small flat head screwdriver or a small plastic trim panel removal tool into one of the two notches.


Pry Out Lens Cover
Lens Cover Removed
Old Light Bulb Exposed
Gently pry out the lens cover from the light housing.

You may need to remove the screwdriver, re-insert it into the other notch and pry again to fully remove the lens cover.

Try to avoid using excessive force to prevent from breaking the lens cover. It should pop out relatively easily.

Set the lens cover aside in a safe place.

Pull Out Old Light Bulb
Old Light Bulb Removed
KHA12V10W 18A10F
If the old light bulb was recently turned on, be careful when you remove the old light bulb. It might still be hot enough to burn your fingers.

If it was recently turned on, allow it to cool off for a few minutes.

The OEM (original equipment manufacturer) light bulb in this 2019 Sorento was marked as part number KHA12V10W 18A10F.

Push In New Light Bulb
Line Up Lens Cover
Re-Insert Tabs - Rear
Push a new number DE3175 festoon style light bulb straight into the socket.

If you would like to have a brighter dome light, install a compatible replacement DE3175 LED light bulb.

I recommend testing the new light bulb before re-installing the lens cover.

Push the "On / Off" button to test the new light bulb.

Tip - If you installed an LED bulb and it 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.

Line up the lens cover with the light housing.

First, re-insert the two plastic tabs on the rear edge of the lens cover back into the housing.

Gently Pop In Front Edge
Test New Light Bulb
Dome Bulb Change Done!
Then carefully snap in the two plastic retaining clips on the front edge of the lens cover.

Double check that the lens cover is securely installed and flush with the light housing at every edge.

To test the new light bulb, press the "On / Off" button again.

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