The Pontiac Phoenix front and rear side marker bulbs both utilize a 194 bulb size across all configurations. The replacement chart covers vehicle production spanning 1977 to 1984 with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Pontiac Phoenix uses the 194 bulb for both the front and rear side marker positions across the 1977-1984 model years.
The 194 is an ANSI-standardized bulb type, meaning its specifications are governed by a recognized North American standard applicable in both the United States and Canada.
The 194 bulb is a miniature wedge type, classified under the T10 designation, which refers to its tubular glass envelope width of 10 eighths of an inch.
The wedge base design of the T10 eliminates the need for a separate metal base, as the glass pinch at the bottom of the bulb itself serves as the retention and contact mechanism within the socket.
The 194 operates at 12 volts, consistent with the standard electrical system voltage found in conventional passenger vehicles of this era.
At 3.78 watts, the 194 draws a relatively low amount of power, which is typical for side marker applications where continuous illumination is required without significant electrical load.
Because the same bulb number applies to both the front and rear side marker positions on the Pontiac Phoenix, a single bulb type serves all four side marker sockets on the vehicle.
The consistent use of the 194 across all eight model years covered in the specifications indicates no mid-generation change in side marker bulb fitment for the Phoenix during this period.
