BMW i8 2020 Bulb Size
Bulb size chart
The 2020 BMW i8 uses an all-LED lighting setup across the exterior and interior on most configurations, so bulb replacement is usually about verifying the correct lamp position rather than matching a traditional halogen bulb number. This page is designed to help you check bulb fitment by lighting location, including the headlight, tail light, brake light, turn signal, license plate light, and cabin lights.
Because BMW offered the i8 with different trim and lighting package combinations by market and body style, the exact service approach can vary. Use this 2020 BMW i8 bulb guide to confirm the bulb type listed for each position before ordering, especially if you are replacing a failed light or planning a cosmetic upgrade.
For the 2020 BMW i8, fitment can differ depending on trim, package, and regional equipment, so always compare the bulb position on your vehicle with the listing on the page before buying. Many exterior lights are LED from the factory, which means the replacement may be a complete LED module rather than a simple replaceable bulb. If your i8 has been modified with aftermarket LED conversions, the original bulb chart may not match what is currently installed. The safest approach is to inspect the installed bulb or module first, then confirm the connector style and housing design before purchase. This is especially important for lighting functions such as the low beam, high beam, daytime running light, turn signal, and rear lamp assemblies, where LED and non-LED setups can be different across markets.
FAQ
Does the 2020 BMW i8 use LED bulbs for most lights?
Yes. The 2020 BMW i8 is listed with LED lighting for the main exterior and interior positions on this page, including the headlights, tail lights, brake lights, turn signals, and several cabin lights.
Why does this page focus on bulb position instead of only bulb size?
Because the i8 can use different lighting hardware by position, trim, and market, the most useful way to verify fitment is by the exact lamp location. That helps you match the correct light before ordering any replacement part.
Are the headlight low beam and high beam bulbs replaceable separately on the 2020 BMW i8?
The page lists both the headlight low beam and headlight high beam as LED. On LED-equipped vehicles, these may be integrated modules rather than standard removable bulbs, so check the actual assembly before purchasing.
Do brake lights and tail lights use the same bulb on this model?
Not necessarily. The page separates the brake light bulb and tail light bulb positions, even though both are listed as LED. That means each function should be verified individually when replacing a rear lamp issue.
What should I check before buying a license plate light bulb for a 2020 BMW i8?
Confirm the lamp housing style and connector on your car, since the license plate light is listed as LED and may be part of a specific module. It is best to inspect the installed unit before ordering a replacement.
Are the front and rear turn signal bulbs the same on the 2020 BMW i8?
This page lists front and rear turn signal light bulb positions separately. Even when both are LED, the assemblies can differ, so do not assume the same part fits both locations.
Can I replace a factory LED light with an aftermarket halogen bulb?
No. If the vehicle is equipped with factory LED lighting, a halogen bulb will not be a direct fit. LED systems usually require the correct LED module or compatible replacement designed for that housing.
What if my 2020 BMW i8 has an aftermarket lighting conversion?
Aftermarket conversions can change the bulb type, connector, or control module requirements. In that case, the factory bulb chart may not match the installed parts, so inspect the current setup before ordering anything.
Which interior lights are listed for the 2020 BMW i8?
The page includes LED listings for the trunk or cargo area light, dome light, map light, interior door light, stepwell light, and instrument panel light, where equipped. These positions should be checked individually because equipment can vary.
How do I make sure I order the correct replacement for a failed LED light?
Start by identifying the exact lighting position, then compare the factory listing with the part currently installed in your vehicle. For the 2020 BMW i8, that is especially important because trim and lighting package differences can affect fitment.
Does the 2020 BMW i8 have side marker lights?
Yes. The page lists both front and rear side marker light bulb positions as LED. If one side is out, verify the exact location and the housing style before replacing the part.
Should I check the installed bulb before purchase even if the page says LED?
Yes. Checking the installed bulb or module is the best way to confirm fitment, especially on a vehicle like the 2020 BMW i8 where lighting packages and market-specific equipment can change the exact replacement needed.
