What Lighting System Does the 2019 BMW i8 Have?
The 2019 BMW i8 features an extensive lighting system with 13 bulb positions. It uses factory LED technology with integrated LED headlight modules. The i8 has been available from 2014 to 2019, and the 2019 model falls in the late-generation years. As a BMW vehicle, it uses a CANbus electrical system that monitors bulb status.
LED Flicker Warning
This vehicle (BMW) is known to use a CANbus system that checks for burnt-out bulbs. Installing standard LEDs may cause them to flicker or trigger a dashboard error.
We highly recommend using a CANbus decoder or "Anti-Flicker" resistors.
Can You Put LED Bulbs in a 2019 BMW i8?
Upgrading the 2019 BMW i8 to LED headlights is straightforward since it uses a single LED Headlights dual-filament bulb for both low and high beams. You only need one pair of LED bulbs to upgrade both functions. Look for a LED Headlights LED kit that specifically supports dual-filament operation to ensure both beams work correctly. Important: BMW vehicles use a CANbus system that detects bulb wattage. Standard LED bulbs may trigger dashboard warnings or flicker. Choose LED kits labeled "CANbus-compatible" or add inline decoder resistors to prevent these issues. For the fog lights, a LED Fog Light LED bulb provides a clean white output that pairs well with LED headlights.
How to Replace Bulbs on a 2019 BMW i8
To remove the headlight bulb, disconnect the wiring harness, then twist the bulb counter-clockwise and pull it straight out of the housing. BMW vehicles are known for tight engine bay clearances around the headlight assembly. You may need to remove the air intake duct, battery cover, or wheel well liner to access the bulbs. Budget 30 to 45 minutes per side for your first replacement. This vehicle has factory-integrated LED headlight modules. These are not user-serviceable bulbs. If your LED headlights fail, the entire headlight assembly or LED module may need to be replaced by a dealer or qualified technician. The fog lights are accessed from underneath the front bumper. You may need to remove a few plastic clips or screws from the fender liner to reach the LED Fog Light fog light socket.

Factory LED headlights on the 2019 BMW i8 are rated for approximately 25,000 to 50,000 hours of use, which translates to roughly 10 to 15 years of normal driving. LED modules rarely burn out suddenly. Instead, they gradually dim over time or develop dead zones within the LED array. At 7 years old, the original bulbs on your i8 are likely overdue for replacement, though LED modules may still have life left. Even if they still illuminate, reduced brightness significantly impacts nighttime safety. When one headlight burns out, replace both sides at the same time. Bulbs from the same batch age at similar rates, and mismatched brightness is distracting to oncoming drivers.
What Bulbs Are Compatible with the 2019 BMW i8?
Using the wrong bulb size can cause improper beam patterns that reduce your visibility and blind other drivers. It can also cause overheating inside the headlight housing, potentially warping the plastic lens or reflector. Always verify the bulb number before purchasing.
