Additional Notes

The 1141 bulb is the most frequently specified size across the Chevrolet Blazer engine compartment light fitments, covering model years 1996 and 1998-2002.
The 1156 bulb is the second most common specification, appearing across model years 1987-1989, 1991, 1995, 1997, and 2003.
Both the 1141 and 1156 are ANSI-standard single-filament bulbs sharing the same BA15s bayonet base, rated at 12V and 21W.
Despite their identical electrical ratings and base type, the 1141 and 1156 are distinct part numbers and are not guaranteed to be interchangeable in all applications.
The 5008 is specified for the Chevrolet Blazer in model years 1993-1994. It is a single-filament bulb with a BA15s bayonet base, rated at 12V, and is described as a lower wattage variant of the 1156.
The 93 bulb is specified for the 1990 model year. It shares the BA15s bayonet base and 12V rating with the other bulbs in these specifications, but carries a rated output of 13W.
All four bulb types listed across these specifications share the BA15s bayonet base, meaning the physical mounting interface is consistent throughout the entire model range covered.
The 5008 and 93 bulbs draw less power than the 1156 and 1141, which may affect light output in the engine compartment despite the shared base fitting.
The shift from the 5008 specification in 1993-1994 to the 1141 in 1996 reflects a change in the rated wattage of the engine compartment bulb between those model years.
All bulb sizes listed in these specifications conform to ANSI standards applicable in both the United States and Canada.
