Additional Notes

The 6411 bulb is the dome light specification for the Buick Encore across the 2013-2020 model years, making it the dominant fitment across this vehicle's listed range.
Both the 6411 and 212-2 are ANSI-standardized festoon bulbs sharing the same SV8.5 base type, meaning they seat into the same style of holder.
Despite sharing the SV8.5 base, the two bulbs differ in body length: the 6411 measures 36mm while the 212-2 measures 41mm, which affects physical fitment within the dome light housing.
The wattage difference between the two bulbs is notable: the 6411 draws 5W while the 212-2 draws 12W, both operating on a 12V circuit.
The 2021 Buick Encore requires the 212-2 bulb rather than the 6411 used in prior years, and the two types are not directly interchangeable due to the difference in body length.
The SV8.5 base designation refers to a festoon-style contact base with an 8.5mm contact width, a format commonly used in interior automotive lighting applications.
