The Oldsmobile Omega front and rear side marker bulbs both utilize a 194 bulb size. The replacement chart covers vehicle production spanning 1973 to 1984.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Oldsmobile Omega uses the 194 bulb for both front and rear side marker positions across the 1973-1984 model years.
The 194 is a miniature wedge bulb, classified under the T10 form factor, which refers to a tubular bulb body roughly 10 millimeters wide at its widest point.
The wedge base design means the 194 bulb is held in place by the socket itself rather than by a separate metal base with pins, a common construction in low-wattage automotive marker applications.
The 194 operates at 12 volts and draws 3.78 watts, placing it in the low-power range typical of side marker and courtesy lighting rather than primary illumination functions.
The 194 is an ANSI-standardized bulb recognized in both the United States and Canada, meaning its electrical and physical specifications conform to a defined industry standard rather than a proprietary format.
Because the front and rear side marker positions on the Oldsmobile Omega share the same 194 bulb size across all listed model years, a single bulb type serves both locations on the vehicle.
The T10 wedge format is widely used across many vehicle makes and model years, which contributes to broad retail availability of the 194 bulb in both incandescent and LED-compatible replacements.
Although the 194 and closely numbered wedge bulbs such as the 168 share the same T10 wedge base, they differ in wattage and are not always interchangeable without affecting circuit load or socket fit tolerances.
