The Chevrolet Monte Carlo side marker utilizes a 194 bulb size for illumination across all listed vehicle applications. Data for the specific component covers the period from 1995 through 2007.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Chevrolet Monte Carlo uses the 194 bulb type across both front and rear side marker positions for every model year listed in the specifications, spanning 1970-2007.
The 194 bulb is an ANSI-standardized miniature wedge type, classified under the T10 form factor, and operates at 12 volts with a power draw of 3.78 watts.
A variant designated 194NA shares the same T10 wedge form factor, voltage, and wattage as the standard 194, but features natural amber-tinted glass rather than clear glass.
The 194NA variant appears in the front side marker position on the Chevrolet Monte Carlo for the 1974-1975, 1978-1980 model years.
The rear side marker position uses the standard 194 bulb without the amber glass variant across all model years listed in the specifications.
Because the 194 and 194NA share identical electrical and physical specifications, the physical fitment is the same, though the amber tinting of the 194NA is a built-in optical property of the glass envelope itself rather than a coating applied externally.
Substituting a clear 194 for a 194NA in a front side marker housing that relies on the bulb's amber glass for color output would alter the emitted light color, as the amber tint in the 194NA is integral to the bulb rather than the lens.
The T10 wedge base design used by both the 194 and 194NA requires no separate metal base or socket pins, as the glass envelope itself acts as the retention mechanism within the housing.
At 3.78 watts, the 194 and 194NA are low-wattage bulbs, a characteristic typical of side marker applications where continuous illumination is required without significant heat or electrical load.
Both the 194 and 194NA carry ANSI standardization recognized in the United States and Canada, meaning bulbs from different manufacturers conforming to this standard are interchangeable in terms of fitment and electrical compatibility.
