BMW 650i Gran Coupe high beam headlight bulbs use H7 and D1S sizes, while low beam headlight bulbs use D1S size. The replacement chart covers 2013 through 2016 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 D1S bulb type is the most frequently specified across these headlight positions, appearing in both high beam and low beam applications across multiple model years of the BMW 650i Gran Coupe.
The D1S is a high-intensity discharge (HID) bulb that operates using a xenon gas arc rather than a tungsten filament, which accounts for its association with the "With HID Headlamps" condition noted throughout the specifications.
The H7 bulb is a halogen type that uses a tungsten filament enclosed in a quartz envelope filled with halogen gas. It is specified for the high beam position on the 2015-2016 model years.
The 2015 BMW 650i Gran Coupe high beam position lists both H7 and D1S as valid bulb sizes, indicating that two distinct headlamp configurations were available for that year, each requiring a different bulb type.
The H7 and D1S bulbs are not interchangeable. They differ in operating voltage, ignition requirements, and physical form factor, meaning the correct bulb is determined strictly by which headlamp system is installed on the vehicle.
The low beam position is specified exclusively as D1S across all listed years (2013-2016), with no halogen alternative noted for any of those model years.
D1S bulbs are self-contained units that integrate the igniter within the bulb itself, distinguishing them from D2S bulbs, which require a separate external igniter. This integration is a relevant fitment consideration when sourcing a replacement.
The high beam position on the 2013-2014 model years is specified only as D1S with HID headlamps, with no halogen variant listed for those years.
