BMW X6 front turn signal bulbs use PY24WNA or 12180 bulb size, while rear turn signal bulbs require H21W size. The replacement chart covers 2008 through 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 PY24WNA is the most frequently specified bulb across the BMW X6 turn signal data, covering the front position for model years 2008-2019. It operates at 12V and 24W, uses a PGU20-4 base, and is the ANSI-standard amber variant of the ECE PY24W, intended for the US and Canadian markets.
The H21W is the sole bulb type listed for the rear turn signal across all rear-position entries. It follows ECE standards, uses a BAY9s base, and operates at 12V and 21W as a single-filament signalling bulb.
For the 2013-2014 BMW X6 front turn signal, the required bulb type depends on the headlamp configuration. Units equipped with HID headlamps take the PY24WNA, while units equipped with LED headlamps take the Philips 12180.
The Philips 12180 is a 12V halogen bulb designated for specialty applications. Its fitment on the X6 is limited to the front turn signal position on 2013-2014 models with LED headlamps, making it a configuration-specific part rather than a general-use replacement.
The PGU20-4 base of the PY24WNA is a wedge-type base with a specific pin offset, which physically prevents installation of non-amber standard PY24W bulbs. This design enforces correct amber output without relying solely on the lens for color.
The BAY9s base used by the H21W is a bayonet-type base with offset pins, which prevents substitution with other single-filament bayonet bulbs such as the more common BA9s. Physical interchangeability with other base types is not possible without modification.
For model years 2008-2012 and 2015-2019, the front turn signal carries a single bulb specification with no headlamp-variant condition, indicating the PY24WNA applies regardless of headlamp type for those years.
The rear turn signal entries cover model years 2008-2014 only, with no rear turn signal entries present for 2015-2019.
