Jeep Commander front and rear side marker bulbs both utilize a 194 bulb size across all configurations. The replacement chart covers 2006 to 2010 vehicle 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 Jeep Commander uses the 194 bulb for both front and rear side markers across its full 2006-2010 model year range.
The 194 is classified as a miniature wedge bulb, designated T10 under standard bulb sizing nomenclature. The T10 label refers to the bulb's tubular shape measured in eighths of an inch.
The 194 operates at 12 volts and draws 3.78 watts, placing it in the low-wattage category typical of parking and marker lighting applications.
The wedge base design of the 194 means the bulb is held in its socket by the tension of the base itself, with no separate metal contact pins or bayonet lugs involved in the connection.
The 194 carries ANSI standardization recognized in both the United States and Canada, meaning the specification reflects a consistent electrical and physical standard across North American markets.
Because the same 194 bulb size is specified for both the front and rear side marker positions on the Jeep Commander, a single bulb type serves all four side marker locations on the vehicle.
The T10 wedge form factor is shared by several bulb numbers beyond the 194, though variations in wattage and voltage ratings among T10-type bulbs mean not all T10 bulbs are interchangeable with the 194 without confirming matching electrical specifications.
