This 2020 Kia Optima bulb size guide helps you verify the correct bulb by lighting position, so you can match the right part before you buy. Because the Optima could be equipped with different lighting setups, the bulb type may change depending on whether your car has halogen headlights or LED headlights, and some exterior lamps can also vary by trim or market.
Use this page as a quick reference for common exterior and interior bulbs on the 2020 Optima, including headlights, turn signals, reverse lights, license plate lights, and cabin bulbs. Checking the bulb location first is the easiest way to avoid ordering the wrong replacement and to make sure the new bulb fits your specific Optima setup.
For the best fitment results, always confirm your trim, lighting package, and headlight type before ordering. The 2020 Optima uses different bulb listings for halogen headlights versus LED headlights, and aftermarket conversions can change what is physically installed in the housing. If you are replacing a bulb that has already failed, it is smart to remove the old bulb and compare the base and connector style before purchase, especially for items like the reverse light, turn signals, and interior lamps. Even when two bulbs share a similar description, the installed part may differ by market, body style, or previous owner modifications.
No. The 2020 Kia Optima can use different headlight bulb types depending on whether it has halogen headlights or LED headlights. The bulb chart on this page separates those setups so you can match the correct low beam and high beam bulb for your car.
For Optima models with halogen headlights, the low beam bulb is listed as 9005. Always verify your headlight type before ordering, since LED headlight models use a different setup.
For 2020 Optima models with halogen headlights, the high beam bulb is also listed as 9005. That makes it especially important to confirm the exact headlight configuration on your vehicle before buying replacements.
LED headlight models use LED-based lighting for several front and rear positions, including the low beam, high beam, daytime running light, parking light, fog light, and some rear lighting functions. The exact bulb-style listing on this page is organized by position to help you identify the correct match.
The back up reverse light bulb is 921. This is a common replacement item and is usually one of the easier bulbs to change once you access the rear lamp assembly.
The front turn signal light bulb is 2357A. If you are replacing one side, it is often a good idea to check the other side as well so both signals match in brightness and color.
The rear turn signal light bulb is 1156A. As with other exterior bulbs, the exact fit can depend on the vehicle’s lighting package, so it is worth confirming the lamp assembly before ordering.
The license plate light bulb sizes are 2825 and 98. Either size may be listed depending on the exact lamp design used on the vehicle.
Common interior bulb listings include 194 and 7441 for the map light, 6418 for the vanity mirror light, glove box light, and trunk or cargo area light, and 6461 for the dome light. These positions are helpful to verify separately because interior lamp sizes can be easy to mix up.
Not always. On halogen headlight models, the brake light bulb is listed as 7528 and the outer tail light bulb is also 7528. On LED headlight models, the brake light and inner tail light positions use LED-based listings instead, so you should check which lighting package your Optima has.
Yes, many owners choose aftermarket LED replacements for some positions, but fitment and compatibility matter. You should confirm bulb base size, housing space, and whether the vehicle may need additional components for proper operation, especially for exterior signal or brake lamps.
Because trim, package, and market differences can change the bulb used in a given position. Physically checking the installed bulb helps confirm the base type and reduces the chance of ordering the wrong part, especially on a 2020 Optima with mixed lighting equipment.
