Additional Notes

The 212-2 is the most frequently specified courtesy bulb across the Chevrolet Silverado lineup, appearing in model years 2007-2014.
The 212-2 is a festoon-type bulb with an SV8.5 base, a 41mm length, and operates at 12V with a 12W output, conforming to ANSI standards for the US and Canada.
The 211-2, specified for the 1999 Silverado, shares the same physical and electrical characteristics as the 212-2, including the 41mm festoon format, SV8.5 base, 12V supply, and 12W rating. Despite these similarities, the two carry distinct ANSI designations and are not listed interchangeably in these specifications.
The 194 is a T10 miniature wedge bulb rated at 12V and 3.78W, representing a significantly lower wattage than the festoon types used in other model years.
The 74 is a T5 miniature wedge bulb rated at 12V and 1.4W, the lowest-wattage type among all bulbs listed in these specifications.
In the 2005 Chevrolet Silverado, courtesy bulb fitment is split by trim level: the 1500 uses the 194, while the 2500/3500 HD uses the 74, making the two sub-models incompatible with each other's bulb type.
The 2014 Silverado specifies the 212-2 for rear courtesy lighting on the 2500/3500 HD only, indicating a position-specific and trim-specific fitment for that year.
The 194 and 74 are both miniature wedge-base bulbs, but their T10 and T5 designations reflect different physical sizes, meaning they are not interchangeable despite sharing the same base style category.
Across the years 2000-2003, the Silverado alternates between the 74 and 194 bulb types, with the 74 used in 2000-2001 and 2003, and the 194 used in 2002 and 2004.
