The Pontiac G6 side marker requires a 194 bulb size for proper installation and function within the lighting assembly. Data for the specified component covers the range from 2005 to 2010.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 194 bulb is the sole bulb type listed across all front and rear side marker positions for the Pontiac G6 in the provided specifications.
The 194 bulb follows the ANSI standard recognized in both the United States and Canada, classifying it as a regionally standardized automotive lamp.
It is a miniature wedge-type bulb, designated T10, which refers to its tubular shape with a wedge base that seats directly into a socket without a separate metal base or pins.
The T10 wedge base design allows the bulb to be removed and inserted by hand, as the wedge base itself acts as the electrical contact within the socket.
The 194 operates at 12 volts, consistent with the standard electrical system voltage found in conventional passenger vehicles.
Its rated wattage of 3.78W places it in the low-power category, typical of side marker applications where continuous illumination is required without significant heat or current draw.
The Pontiac G6 uses the same 194 bulb size in both the 2005 and 2010 model years across both front and rear side marker positions, indicating no variation in bulb fitment between those years.
Because the front and rear side marker positions share the same bulb type, a single 194 bulb serves as a direct fitment for all four side marker sockets on the vehicle.
The T10 wedge format is widely used across many vehicle makes and models, meaning 194 bulbs sourced from general automotive supply are physically compatible with the G6 side marker sockets as specified.
Substituting a bulb with a different wattage rating in a T10 socket may affect socket integrity or electrical load compatibility, as the 3.78W rating is specific to the 194 designation.
