Additional Notes

The PY24WNA is the sole bulb type across all listed years of the BMW ActiveHybrid 5 front turn signal position, spanning the full 2012-2016 model range.
PY24WNA is an ANSI-standard bulb rated for use in the United States and Canada, distinguishing it from its ECE counterpart, the PY24W, which serves other markets.
The bulb operates at 12 volts and 24 watts, which is consistent with standard automotive low-voltage electrical systems.
PY24WNA carries a factory-amber glass envelope, meaning the amber turn signal color is produced by the bulb itself rather than by a colored lens or housing.
The PY24WNA uses a PGU20-4 base, a wedge-style pin configuration that is not universally interchangeable with other common automotive bases such as the BAU15s or BA15s found in some competing amber turn signal bulbs.
For the 2014-2016 BMW ActiveHybrid 5, the PY24WNA fitment is specifically noted under the condition of HID headlamp equipment, indicating that headlamp technology is a relevant variable in front turn signal bulb selection for those model years.
The 2012-2013 model years carry no headlamp-type qualifier alongside the PY24WNA designation, reflecting that the specification applies without a conditional equipment note for those years.
