BMW Motorcycle G310R uses a 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2016 to 2019 production years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9003 bulb is the sole bulb type specified across all headlight positions on the BMW Motorcycle G310R for the 2016-2019 model years.
The 9003 is a dual-filament halogen bulb, meaning a single bulb unit contains two separate filaments: one rated at 60W for high beam operation and one rated at 55W for low beam operation.
Because the 9003 serves both the high beam and low beam positions on the G310R, both positions draw from the same physical bulb type, which simplifies replacement parts inventory.
The 9003 operates on a 12V electrical system, consistent with standard 12-volt motorcycle electrical architecture.
The 9003 uses a P43t base, which is a bayonet-style mount with a 43mm flange. This base type is specific to the 9003 and its international equivalent, the H4, and is not interchangeable with single-filament base types such as P14.5s or P15d.
The 9003 designation is an ANSI standard classification used in the United States and Canada. The H4 bulb is its international counterpart and shares the same filament configuration, voltage, and wattage ratings, though packaging and labeling differ by market.
