Pry Out Lens Cover
This automotive maintenance tutorial was specifically written to assist owners of the 4th generation (2016, 2017, 2018, 2019 and 2020 model years) Kia Optima sedan in changing a burnt out dome light bulb located in the housing attached to the headliner above the rear passenger seats.

Owners of other Kia, Hyundai or Genesis vehicles such as the Niro, Sportage, Sedona, Telluride, Sorento, Rio, Forte, Soul, K900, Cadenza, K5, 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 "festoon" style light bulb is part number DE3175 which is available from various manufacturers such as Sylvania, Philips and Bosch.

If you would like to have a brighter dome light, install a DE3175 LED unit which will last a lot longer than a traditional incandescent bulb.

The tools that may be needed to remove the light housing and access the bulb include a flat head screwdriver and / or a small plastic pry bar tool.

To prevent from scratching the plastic surfaces, you can either cover the tip of your screwdriver with a thin micro fiber cloth or instead use a plastic trim panel removal tool.

Insert the blade of the screwdriver into one of the two small notches on the front edge of the lens cover.

Gently pry out the lens cover. You may need to re-insert the screwdriver into the second notch and pry again.

Try to avoid using excessive force. The lens cover should pop out relatively easily.

Old Light Bulb Exposed
Once the front edge of the translucent plastic lens cover is loose, pull the two tabs on the rear edge out of the light housing.

Set the lens cover aside in a safe place.

If the old light bulb was recently turned on, be careful when you remove it. The bulb might still be hot enough to burn your fingers.

Grasp the old bulb with your thumb and forefinger before pulling it straight out of the socket.

The OEM (original equipment manufacturer) light bulb in this 2019 Optima LX FE was marked as part number KHA12V10W 18F25B.

Pop In Clips - Front
Push a new number DE3175 festoon style light bulb straight into the socket.

I recommend upgrading the dome light with a brighter DE3175 LED bulb that will last much longer than a traditional incandescent bulb before burning out.

Make sure the new bulb is fully seated between the electrical contacts.

Line up the lens cover with the opening in the light housing.

First, re-insert the two tabs on the rear edge into the housing first.

Then gently snap in the retaining clips on the front edge of the lens cover.

Test New Light Bulb

Bulb Change Complete
You should feel or hear the two retaining clips "click" securely into place.

Double check that the lens cover is flush with the rest of the light housing at every edge.

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

Tip - If you installed an LED bulb and it doesn't work, try removing the bulb from the socket, rotate it 180 degrees and install 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.

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