2014 Kia Optima Headlight Bulb Size & LED Upgrade

2014 Kia Optima Headlight Bulb Size

Kia freshened up the Optima for 2014 with a revised grille, new headlight housings, and updated interior materials that kept the mid-size sedan competitive against the Hyundai Sonata and Honda Accord. The 2014 Kia Optima headlight bulb size is H11 for the low beams, 9005 for the high beams, and H11 for the fog lights. The LX trim remains the value leader in the lineup, though every version benefits from the same bulb fitment.

If you are shopping for 2014 Kia Optima LED headlights, the most common reason is that the original halogen bulbs have dimmed noticeably since new. Halogen filaments thin out with use, reducing output by up to 30 percent before the bulb actually burns out. An LED conversion kit restores that lost brightness and pushes well beyond the original halogen output, and every HID Nation kit ships free with a lifetime warranty.

Best LED and HID Kits for the 2014 Kia Optima

An LED headlight upgrade for the 2014 Optima plugs directly into the factory H11 low beam and 9005 high beam sockets. No wiring splices, no relay harnesses, and no headlight housing changes. The modern 6000K white output makes road markers, pedestrians, and wildlife far easier to spot at night. Most owners wrap up both sides in under 20 minutes.

HID xenon kits suit drivers who want maximum beam density and throw distance. A slim ballast connects between each bulb and the factory harness, adding roughly ten minutes to installation. Once the HID bulbs reach full temperature, they produce an intense, far-reaching light column that outperforms LED in total lumen output at distance.

HID Nation backs every conversion kit with free shipping and a lifetime warranty, giving you confidence that the upgrade is protected for the long haul.

Frequently Asked Questions

What headlight bulb size does the 2014 Kia Optima take?

The 2014 Kia Optima takes H11 bulbs in the low beam position, 9005 bulbs in the high beam position, and H11 bulbs in the fog lights. This applies to the LX, EX, and SX trims equally.

Can I install LED headlights on my 2014 Kia Optima myself?

Absolutely. LED kits for the 2014 Optima are true plug-and-play replacements. You reach behind each headlight housing from the engine bay, twist out the old halogen, and insert the LED bulb into the same socket. The included LED driver is small enough to fit behind the dust cap on most housings. No tools beyond your hands are needed.

Does the 2014 Optima share bulb sizes with the 2013 model?

Yes. The 2013 and 2014 Kia Optima both use H11 low beams, 9005 high beams, and H11 fog lights. Although the 2014 received a front-end refresh with different headlight styling, the actual bulb sockets are identical between the two model years. The same LED or HID kit works on both.

What is the difference between LED and HID headlights for the 2014 Optima?

LED kits light up instantly, draw less power than halogen, and produce very little heat. HID kits deliver higher peak lumen output and deeper beam throw, but they need a few seconds to reach full brightness and require a ballast per side. For the 2014 Optima, most daily commuters prefer LED for its simplicity, while drivers logging frequent highway miles at night may favor HID.

What fog light bulb does the 2014 Kia Optima use?

The 2014 Kia Optima uses H11 fog light bulbs, the same size as the low beams. You can order a single H11 LED kit and use it in either the low beam or fog light position, which also makes it easy to match the color temperature across the front of the vehicle for a clean, uniform look.
