For the 2020 Kia Rio, the low- and high-beam bulbs depend on the headlight design. Models with projector-type headlights use 9005 bulbs for both low and high beams. Models without projector-type headlights use 9003 bulbs for both functions. Confirm the headlight style before ordering, since these are different fitments.
The front fog lights use 9006 bulbs. Front turn signals are 7507 with projector-type headlights and 2357A without them. Rear turn signals use 7507.
Lighting at the rear also varies by headlight configuration: projector-equipped models use LED tail and brake lights, while non-projector models use 7528 bulbs for both. The center stop light and license plate light use 2825, and the reverse lights use 921. Interior fitments include 6461 for the dome, trunk, and vanity lights, 6418 for the glove box, and 194 or 7441 for the map lights.
