Chevrolet Captiva Sport front and rear side marker bulbs use a 168 size bulb for replacement applications. The replacement chart covers 2012 to 2015 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 168 bulb is the sole bulb type specified for side marker lighting across all listed model years of the Chevrolet Captiva Sport.
The 168 bulb follows the ANSI standard recognized in both the United States and Canada, placing it within a regulated specification framework for electrical and photometric performance.
It is a miniature wedge bulb of the T10 form factor, which refers to a tubular glass envelope approximately 10 millimeters wide with a wedge-style base that seats directly into a socket without a separate metal base or pins.
The bulb operates at 12 volts and draws 4.9 watts, consistent with low-power marker lighting applications where continuous illumination is required without significant electrical load.
The Chevrolet Captiva Sport (2012-2015) uses the same 168 bulb specification for both the front and rear side marker positions, meaning a single bulb type serves all four side marker locations on the vehicle.
The T10 wedge base format is shared by several bulb designations, including the 194 and 147 types, which carry different wattage ratings. Substituting a non-168 T10 bulb may result in incorrect light output or electrical incompatibility even if the base physically fits the socket.
