This page helps you verify bulb sizes for the 2021 Hyundai Ioniq EV by lighting position, so you can match the correct replacement before you buy. Because trim and lighting packages can vary by market and body style, it is always smart to confirm the exact socket and bulb type on your vehicle.

For this model year, the listed bulb sizes cover common exterior and interior locations such as headlights, turn signals, brake lights, reverse lights, license plate lights, dome lights, and cargo area lighting. Use the position-specific chart to narrow down the correct fit and avoid ordering the wrong bulb.

Fitment can differ between trims and regional versions of the 2021 Hyundai Ioniq EV, especially when comparing halogen and LED setups or factory lighting packages.

Before purchasing, check the bulb currently installed in the vehicle and compare it with the chart, since even a matching size code does not always guarantee compatibility with a modified housing or retrofit kit.
