The Chevrolet Lumina APV front side marker bulb uses a 194NA size while the rear side marker bulb requires a 194 size. The replacement chart covers vehicle production spanning 1990 to 1996 with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Chevrolet Lumina APV uses two closely related bulb types across its side marker positions: the 194NA for the front and the 194 for the rear, both of which are T10 miniature wedge bulbs operating at 12V and 3.78W under the ANSI standard recognized in the US and Canada.
The T10 wedge base is a common automotive format in which the bulb's glass envelope tapers to form the electrical contact directly, eliminating the need for a separate metal base or pins.
The front side marker position on the Lumina APV uses the 194NA bulb across all model years from 1990-1996.
The "NA" suffix in the 194NA designation indicates natural amber glass, meaning the color is produced by the tinted envelope itself rather than by an amber-colored lens housing.
Because the 194NA produces amber light through its glass rather than through an external lens, substituting a standard 194 bulb in the front position would alter the emitted color if the housing lens is clear.
The rear side marker position on the Lumina APV uses the standard 194 bulb, which shares the same T10 wedge form factor and identical electrical ratings as the 194NA but has a clear glass envelope.
Rear side marker data for the Lumina APV covers the 1994-1996 model years.
Despite their physical and electrical compatibility, the 194 and 194NA are not interchangeable in all positions, as the amber tinting of the 194NA is a functional specification tied to regulatory color requirements for front side markers.
