The Oldsmobile Cutlass Ciera uses 194 bulb size for both front and rear side marker applications. The replacement chart covers 1982 to 1990 production years 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 Oldsmobile Cutlass Ciera uses the 194 bulb size across all listed front side marker positions, spanning model years 1982-1990.
The 194 bulb is an ANSI-standardized type recognized in both the United States and Canada, meaning it conforms to a defined set of electrical and physical parameters shared across manufacturers.
This bulb follows the T10 miniature wedge form factor. The wedge base design relies on the glass envelope itself being pinched at the base to form the electrical contacts, rather than using a separate metal base with pins.
The 194 bulb operates at 12 volts and draws 3.78 watts, placing it in the low-wattage category typical of side marker applications where continuous illumination is required without significant heat output.
The front side marker position on the Cutlass Ciera uses the 194 bulb consistently across all nine model years listed in the specifications, indicating no change in bulb fitment throughout that production span.
The rear side marker position on the Cutlass Ciera (Oldsmobile Cutlass Ciera) also uses the 194 bulb, making the front and rear side marker positions interchangeable in terms of bulb type.
Because the front and rear side marker positions share the same 194 bulb specification, a single bulb type serves both locations on the vehicle, though the housing sockets and lens assemblies at each position are separate components.
The T10 wedge base is a widely used standard in automotive lighting, and the 194 designation specifically identifies a defined wattage and voltage rating within that base family, distinguishing it from other T10 variants such as the 168, which carries a different wattage rating.
