The Avanti II front and rear side marker bulbs both utilize a 194 bulb size across all configurations. The replacement chart covers vehicle production spanning 1965 to 1973 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 Avanti II uses the 194 bulb for both front and rear side marker positions across all listed model years, 1965-1973.
The 194 is an ANSI-standardized bulb type recognized across the United States and Canada, operating at 12 volts and 3.78 watts.
The 194 bulb follows the T10 miniature wedge form factor, a design that uses a tapered plastic base rather than a metal pin or bayonet fitting for socket retention.
Because the front and rear side marker positions share the same 194 bulb specification on the Avanti II, a single bulb type serves both locations without substitution.
The T10 wedge base is a widely produced form factor, and the 194 designation identifies a specific wattage and voltage rating within that family rather than the physical base type alone.
At 3.78 watts, the 194 operates at a relatively low power draw, consistent with its role as a marker lamp rather than a primary illumination source.
