Additional Notes

The 211-2 is the luggage compartment bulb size for the Cadillac CTS across the 2018-2019 model years.
The 211-2 is an ANSI-standardized bulb type, meaning its specifications are governed by a formal industry standard shared across the US and Canadian markets.
The 211-2 is a festoon-style bulb, a form factor characterized by a cylindrical tube with contact caps at each end rather than a screw or bayonet base.
The 211-2 measures 41mm in length, which is a critical fitment factor, as festoon bulbs must match the span of the holder to make proper contact.
The 211-2 uses an SV8.5 base, a designation that refers to the size and style of the end caps on the festoon body.
The 211-2 operates at 12 volts and 12 watts, consistent with standard 12V automotive electrical systems.
