This 2011 Kia Optima bulb size guide helps you verify the correct bulbs by lighting position, so you can replace the right part the first time. Because trim level, lighting package, market, and body style can change the fitment, it is important to match the bulb to the exact lamp location on your car.
Use this page as a quick reference for the 2011 Kia Optima’s exterior and interior lights, including headlight, brake light, tail light, reverse light, license plate light, map light, dome light, and cargo area bulbs. The chart below is organized by position to make bulb checks and replacements easier.
Fitment can vary between halogen and HID-equipped cars, and some bulbs are listed differently depending on the lighting package. Before buying, confirm whether your Optima has halogen headlights or HID headlights, and compare the installed bulb to the chart whenever possible. This is especially important if your car has been modified with aftermarket LED replacements, because conversion kits and retrofit housings may change the bulb type or physical fit. Checking the old bulb, connector, and housing style before ordering can save time and prevent returns.
