BMW i8 2017 Bulb Size
Bulb size chart
The 2017 BMW i8 uses an LED-heavy lighting setup, so this page is designed to help you verify bulb sizes by lighting position before you buy replacements. Whether you are checking exterior lamps or interior lights, the goal is to match the correct bulb type to the exact location on the car.
Because the i8 can vary by market, trim, and lighting package, the bulb chart for this year should be used as a position-by-position reference rather than a one-size-fits-all guide. That is especially useful for items like the headlight, tail light, turn signal, license plate, and cabin lighting positions listed for the 2017 BMW i8.
For fitment, always confirm the exact trim and lighting package on your 2017 BMW i8 before ordering parts, since some lighting assemblies and interior lamps can differ by market and body style. Many positions on this car are LED from the factory, so replacement may mean swapping an entire LED module or assembly instead of a simple bulb. If you are considering an aftermarket LED conversion, check for compatibility with the vehicle’s electronics, warning messages, and beam pattern before installing anything. The safest approach is to inspect the installed bulb or module first and compare it with the chart and the original part information before purchase.
FAQ
Does the 2017 BMW i8 use LED bulbs in most lighting positions?
Yes. The bulb chart for the 2017 BMW i8 shows LED lighting for the main exterior and many interior positions, including the low beam, high beam, brake light, tail light, turn signals, license plate light, and several cabin lights.
Why should I verify bulb size by lighting position on this car?
Because the 2017 BMW i8 uses different bulb types depending on the location. A bulb that fits the license plate light will not necessarily fit the dome light, rear turn signal, or headlight area, so checking by position helps avoid ordering the wrong part.
Are the low beam and high beam bulbs on the 2017 BMW i8 replaceable as standard bulbs?
The chart lists both the headlight low beam and high beam as LED. On many LED-equipped vehicles, these may be integrated modules rather than traditional replaceable bulbs, so it is important to inspect the installed setup before buying a replacement.
Do trim levels or packages affect bulb fitment on the 2017 BMW i8?
Yes. Trim and lighting package can vary by market and body style, and that can affect which LED modules or lamp assemblies are installed. Always compare your vehicle’s exact equipment with the bulb chart.
What should I check before replacing a brake light or tail light bulb?
Confirm whether your 2017 BMW i8 uses a serviceable LED module or a sealed lamp assembly for that position. Since the chart lists these as LED, the replacement may involve the entire unit rather than a loose bulb.
Can I use aftermarket LED bulbs in the turn signal positions?
Sometimes, but fitment and electronics compatibility matter. The front and rear turn signal positions are listed as LED on the 2017 BMW i8, so aftermarket changes should be checked carefully for error messages, hyperflash, or beam/visibility issues.
What about the license plate light on the 2017 BMW i8?
The license plate light is listed as LED. If you are replacing it, verify the exact lamp style on your car, because some versions use a complete LED fixture instead of a standard bulb socket.
Are the interior lights also LED on this model year?
Yes, the chart includes LED for the trunk or cargo area light, dome light, map light, interior door light, stepwell light, and instrument panel light where equipped. These can still vary by package, so checking the installed part is recommended.
How do I know if my car has the optional instrument panel light?
Not every 2017 BMW i8 will have the same interior lighting equipment. If the instrument panel light is present on your car, confirm the installed LED type before ordering a replacement.
Is the back up reverse light on the 2017 BMW i8 an LED bulb?
Yes, the bulb chart lists the back up reverse light as LED. As with other exterior lamps on this car, the replacement may be a module or assembly rather than a simple bulb swap.
What is the best way to avoid ordering the wrong bulb for this BMW?
Use the bulb chart as a guide, then verify the installed bulb or module on your specific 2017 BMW i8. Matching the lighting position, trim, and market configuration is the best way to confirm fitment before purchase.
