BMW i3 2018 Bulb Size
Bulb size chart
This 2018 BMW i3 bulb size guide is designed to help you confirm the correct replacement bulb by lighting position, so you can match the right fit before you buy. Whether you are replacing an exterior lamp or a small interior bulb, this page organizes the common bulb types used on the 2018 i3 in a simple, location-based format.
The 2018 BMW i3 uses a mix of LED lighting and a few conventional bulb types depending on the lamp location and equipment level. Because trim, lighting package, market, and body style can change the exact setup, it is a good idea to compare the bulb chart with the bulb already installed in your vehicle before ordering replacements.
For best fitment, always check whether your 2018 BMW i3 has factory LED lighting or a halogen-style bulb in a specific position, since some locations may differ by trim or package. This is especially important if you are considering aftermarket LED conversions, because a bulb that physically fits may still need the correct base type, polarity, or CANbus-compatible design to work properly. If you are unsure, remove the installed bulb and compare its shape and markings before purchase, especially for items such as the dome, stepwell, glove box, map, and front turn signal bulbs where option differences may apply.
