2013 Kia Optima Headlight Bulb Size
Peter Schreyer's tiger-nose grille made the third-generation Optima the car that had people asking "wait, that's a Kia?" and the 2013 model year carried that momentum forward with sharp styling and available 2.0-liter turbo power. The 2013 Kia Optima headlight bulb size is H11 for the low beams, 9005 for the high beams, and H11 for the fog lights. Whether you drive the efficient 2.4L base or the punchy SX Turbo, these bulb positions are the same across all trims.
Searching for 2013 Kia Optima LED headlights usually means the factory halogens have started showing their age. After several years on the road, halogen filaments lose output gradually, dimming well before they actually fail. A plug-and-play LED conversion kit restores full brightness and adds a modern white beam, all covered by HID Nation's lifetime warranty with free shipping on every order.
Best LED and HID Kits for the 2013 Kia Optima
LED headlight kits for the 2013 Optima connect directly to the stock H11 and 9005 wiring harnesses. There is no cutting, no relay box, and no modification to the headlight housing. You get a crisp 6000K daylight-white beam that makes lane markings and road signs far more visible than the warm yellow of halogen. Plan on roughly 15 to 20 minutes per side for the swap.
HID xenon conversion kits push even more raw lumen output and throw light deep down the road, which is ideal for highway commuting in the dark. Each bulb pairs with a slim ballast that tucks behind the housing. Installation takes slightly longer than LED, but the dense beam pattern is hard to beat for sheer reach.
Every HID Nation kit ships free and is backed by a lifetime warranty, making the upgrade a zero-risk decision for your third-gen Optima.
Frequently Asked Questions
What headlight bulb size does the 2013 Kia Optima use?
The 2013 Kia Optima uses H11 bulbs for the low beams, 9005 bulbs for the high beams, and H11 bulbs for the fog lights. This fitment applies to the LX, EX, and SX Turbo trims alike.
Are LED headlights a direct fit on the 2013 Kia Optima?
They are. LED conversion kits for the 2013 Optima use the same H11 base as the factory halogen bulb, so the swap is completely plug-and-play. The compact LED driver fits behind the dust cap or mounts just outside the housing. No rewiring, no adapter harness, and no dealer appointment needed.
Will the 2013 Optima throw a dashboard error with LED bulbs?
Most 2013 Kia Optima owners do not experience dashboard warnings after switching to LED headlights. The vehicle's electrical system generally accepts the lower power draw without triggering a bulb-out code. In the rare event a warning appears, a simple resistor kit resolves it.
How do the 2013 Optima headlight bulbs compare to the 2014 model?
Both the 2013 and 2014 Kia Optima share the same H11 low beam, 9005 high beam, and H11 fog light fitment. The 2014 received a mid-cycle front-end refresh with restyled headlight housings and grille, but the bulb sockets remained identical. An LED kit purchased for one year will work on the other.
What fog light bulb does the 2013 Kia Optima take?
The 2013 Kia Optima uses H11 bulbs in the front fog light position. Since the low beams also use H11, you can order the same LED kit for both locations and get a matched white appearance across the entire front lighting setup.
