2019 Kia Optima Headlight Bulb Size
The 2019 model marks the final year the Kia Optima carried the Optima name before being rebranded as the K5 for the 2021 model year, making it the last of a long-running mid-size sedan nameplate. The 2019 Kia Optima headlight bulb size is H11 for the low beams, 9005 for the high beams, and H11 for the fog lights. This fitment is the same whether you drive the base LX or the sportier SX Turbo.
Owners looking into 2019 Kia Optima LED headlights want to squeeze the best possible performance out of the last Optima. Factory halogen bulbs lose brightness over time, and a fresh LED kit from HID Nation brings the output back and then some. Free shipping and a lifetime warranty come standard with every order.
Best LED and HID Kits for the 2019 Kia Optima
LED kits for the 2019 Optima connect to the factory H11 and 9005 harnesses without any wiring changes. The bulbs install exactly like a standard halogen replacement, and the integrated driver unit is small enough to fit within the headlight housing on most trims. Once powered on, you get a 6000K white beam that makes an immediate visual difference over the warm yellow of halogen.
HID xenon kits are the choice for drivers who want the absolute deepest beam throw available. A compact ballast mounts near each housing, and the xenon arc produces a broad, intense light pattern that excels on dark stretches of highway. Plan on about 30 to 40 minutes total for both sides.
HID Nation includes free shipping and a lifetime warranty with every headlight kit, so your last-year Optima gets top-tier lighting without any risk.
Frequently Asked Questions
What headlight bulb size does the 2019 Kia Optima take?
The 2019 Kia Optima takes H11 bulbs for the low beams, 9005 bulbs for the high beams, and H11 bulbs for the fog lights. All trims from the LX through the SX Turbo share this bulb configuration.
Is the 2019 Optima the last model year before the K5?
It is. The 2019 Kia Optima was the final model year to use the Optima nameplate. Kia replaced it with the all-new K5 starting in 2021, which brought a completely different design and headlight housing. However, the 2019 Optima still uses the same proven H11 and 9005 bulb sockets, and aftermarket LED and HID kits remain widely available.
How quickly can I swap the headlight bulbs on my 2019 Optima?
An LED bulb swap on the 2019 Kia Optima takes roughly 10 to 15 minutes per side. You access each bulb from behind the headlight assembly under the hood, twist out the old halogen, and insert the LED replacement into the same socket. No special tools or mechanical experience are required.
Do LED headlights on the 2019 Optima cause CANBUS errors?
The 2019 Optima does not typically trigger CANBUS bulb-out warnings when LED headlights are installed. The vehicle's electrical system usually recognizes the LED draw without issue. On the rare occasion a warning does appear, a plug-in resistor kit quickly resolves it.
What fog light bulb fits the 2019 Kia Optima?
The 2019 Kia Optima uses H11 bulbs in the fog light position. This is the same size as the low beams, so a single H11 LED kit can be used for either application. Upgrading both positions at once gives you a matched white appearance across the front of the vehicle.
