The BMW i4 is a fully electric fastback sedan with lighting details that can vary by model year, trim, and equipment package. If you are trying to replace a headlight, fog light, turn signal, brake light, or interior bulb, this model page is a starting point that helps you narrow down the correct year before you check the exact fitment.
Use this BMW i4 page to choose the right year page for exact bulb sizes and socket information. For the i4, the available year pages on bulbsize.org are 2023 and 2022, and that year-specific guidance is where you will find the most accurate bulb chart for your vehicle.
Because the BMW i4 can differ by trim and lighting package, the same model name does not always mean the same bulb setup. Features such as LED lighting, adaptive headlamps, or optional packages can change what is installed, so always confirm the year page and match it to your vehicle’s trim and equipment before ordering replacement bulbs.
FAQ
Why does the BMW i4 model page not list exact bulb sizes?
Model pages are meant to guide you to the correct year page first. Exact bulb sizes can change by model year, trim, and lighting package, so the year-specific page gives the most reliable fitment details for your BMW i4.
Which BMW i4 years are covered on this page?
This model page currently points to the 2023 and 2022 BMW i4 year pages. If your vehicle is one of those model years, use the matching year page to find the exact bulb chart.
How do I find the right bulb for my BMW i4?
Start by confirming the model year, then check the year page for your BMW i4. From there, match the bulb location, such as low beam, high beam, turn signal, brake light, reverse light, or interior light, to the chart provided for that year.
Do different BMW i4 trims use different bulbs?
Yes, they can. Trim level and equipment packages may affect the lighting setup, especially on vehicles with advanced LED systems or optional lighting features. That is why the year page is the best place to verify exact bulb fitment.
Can I use the same bulb chart for a 2022 BMW i4 and a 2023 BMW i4?
Not always. Even when the model name is the same, bulb fitment can change between years. Always check the specific 2022 or 2023 year page before buying replacement bulbs for your BMW i4.
What if my BMW i4 has LED headlights?
If your BMW i4 has LED headlights, the serviceable bulb options may be different from vehicles with other lighting setups. Some LED assemblies use integrated components, while others still have replaceable bulbs for certain functions. Check the year page for the exact configuration.
Does the BMW i4 page help with interior bulbs too?
Yes, the model page helps you get to the correct year page for interior and exterior bulb guidance. Once you open the matching year page, you can look for the exact bulb sizes used for cabin lights, cargo area lights, and other interior locations.
What should I do if I am not sure which year my BMW i4 is?
Check the vehicle registration, VIN, door jamb label, or owner documentation to confirm the model year. Once you know whether your car is a 2022 or 2023 BMW i4, use the matching year page for exact bulb information.
Are bulb sizes the same for all exterior lights on the BMW i4?
No. Different exterior lighting positions often use different bulb types or integrated LED units. A brake light, turn signal, side marker, or reverse light may not share the same fitment, so use the year chart for each specific location.
Why is it important to match the exact year page before ordering bulbs?
Ordering from the correct year page reduces the chance of getting the wrong bulb type, socket, or fitment. This is especially important on the BMW i4, where lighting equipment can vary by year and package.
Can optional packages affect BMW i4 bulb fitment?
Yes. Optional lighting packages and equipment upgrades can change the bulb setup or the way a light assembly is built. The year page helps you compare the exact configuration for your BMW i4 before you buy replacement bulbs.
What is the best way to use this BMW i4 page?
Use this page as a model-level guide, then open the year page that matches your car. That approach gives you the most accurate bulb-size information and helps you avoid guessing when replacing bulbs on your BMW i4.
