Additional Notes

The Chevrolet Blazer luggage compartment uses the 211-2 bulb across the 1995-2003 model years, making it the more frequently specified of the two bulb types found in these specifications.
The 211-2 is a festoon-type bulb, meaning it is cylindrical and held in place by contact at each end rather than by a base inserted into a socket. Its length is 41mm and it uses an SV8.5 base, operating at 12 volts and 12 watts.
The 1142 bulb is specified for the Chevrolet Blazer luggage compartment across the 1987-1991 model years.
The 1142 is a dual-filament bulb with a BAY15d bayonet base, rated at 12 volts with a 21/5W output across its two filaments. It is classified as a variant of the 1157 bulb type.
Both the 211-2 and the 1142 conform to ANSI standards applicable in the United States and Canada.
The two bulb types are not interchangeable. The 211-2 uses a festoon mounting with an SV8.5 base, while the 1142 uses a BAY15d bayonet base, and the socket designs for each are physically incompatible.
The dual-filament construction of the 1142 distinguishes it from the single-filament 211-2, a difference that also reflects a significant gap in wattage between the two types.
