Additional Notes

The Volkswagen Eos uses two distinct back up light bulb sizes across its model years, with the 7506 fitted to 2007-2011 models and the 921 fitted to 2012-2016 models.
The 921 is an ANSI-standardized bulb type, meaning its specifications are governed by a recognized North American standard applicable in both the United States and Canada.
The 921 bulb follows a T15 wedge form factor. A wedge base bulb has no separate metal pins; instead, the glass envelope itself is pinched at the base and held in place by tension within the socket.
The 921 operates at 12 volts and draws 16 watts, which is consistent with standard automotive electrical systems.
The 921 and 7506 are not the same bulb type, and the two are not interchangeable despite both being used as back up light bulbs in the Volkswagen Eos across different model years.
