The Chevrolet Lumina side marker utilizes a 194 bulb size for illumination across all listed vehicle applications. Data provided for the specific component covers the period from 1995 through 2001.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Chevrolet Lumina uses two distinct bulb types across its side marker positions: the 194 and the 24, both of which conform to ANSI standards recognized in the United States and Canada.
The 194 is a T10 miniature wedge bulb rated at 12V and 3.78W. Its wedge-style base requires no separate metal socket pins, as the glass envelope itself acts as the retention mechanism.
The 24 is a single-filament bulb with a BA9s bayonet cap base rated at 12V and 2W. The BA9s base uses a small single-pin bayonet fitting, which is physically incompatible with the wedge socket used by the 194.
Because the 194 and the 24 use different base types, they are not interchangeable with each other despite both operating on a 12V system.
The 194 is the more widely used of the two types across the Lumina's side marker positions, appearing in both front and rear rear marker roles across the majority of model years covered in the specifications.
On the Chevrolet Lumina, the rear side marker position uses the 194 bulb across all model years from 1990-2001 without variation.
The front side marker position on the Lumina shifted from the 24 bulb to the 194 bulb between the 1994 and 1995 model years, aligning the front fitment with the rear for 1995-2001.
For the 1990-1994 Lumina, the front and rear side marker positions require different bulb types, with the front using the 24 and the rear using the 194.
From 1995-2001, both the front and rear side marker positions on the Lumina share the same 194 bulb specification, making the front and rear fitments identical for those years.
The 3.78W output of the 194 is notably higher than the 2W output of the 24, reflecting a difference in luminous output between the two bulb types used across the Lumina's production run.
