BMW i8 2015 Bulb Size
Bulb size chart
This 2015 BMW i8 bulb guide is designed to help you verify the correct bulb type by lighting position, so you can replace the right lamp without guessing. Because the i8 uses LED lighting in many exterior and interior locations, the exact fit can depend on the specific light position and the equipment fitted to the car.
Use this page as a quick reference for common bulb locations on the 2015 BMW i8, including the low beam, high beam, brake light, turn signals, license plate lights, daytime running lights, reverse lights, and interior lamps. Matching the bulb by function is especially helpful on a car like the i8, where trim and lighting package differences can affect replacement needs.
Before buying replacements for a 2015 BMW i8, check the installed bulb or module first, since trim level, market, and body style can change fitment. Some positions may use factory LED units rather than traditional replaceable halogen bulbs, and aftermarket LED conversions may require different connectors, resistors, or coding to work correctly. If the car has already been modified, the safest approach is to confirm the original part on the vehicle before ordering anything.
