Kia Optima Plug-In Hybrid Bulb Size By Years

When I first looked up bulb sizes for my 2020 Kia Optima, I wanted a simple, reliable reference that saved time at the store. Think of this list as a compact mental model: it matches common lamp and signal bulbs to the Optima’s locations, so you can quickly identify what to order or bring to a DIY swap. From my experience, that small clarity prevents trips and guesswork. As you expand from a single fog lamp to headlights and interior lights, the chart helps you compare sizes and types at a glance. A useful rule of thumb is to double-check the owner’s manual for trim-specific notes, then use the chart to pick compatible bulbs. Quick recap: the list aims to make bulb replacement straightforward and confidence-building. I may earn a small commission if you purchase through the links provided, at no additional cost to you.
