Additional Notes

The courtesy bulb specifications for the Chevrolet Colorado span the 2004-2024 model years and reference four distinct bulb sizes: 194, 12961, 192, and 168.
All four bulb types share the T10 miniature wedge form factor, which is a small, wedge-shaped base design that seats directly into a socket without a separate metal base or locking mechanism.
Three of the four bulb types, the 194, 192, and 168, carry ANSI designations recognized across the United States and Canada, while the 12961 is identified by a Philips part number rather than an ANSI standard.
The 12961 bulb specifies a W2.1x9.5d base, which is the formal IEC designation for the standard T10 wedge base. This base type is physically compatible with the same socket family used by the ANSI-coded bulbs in these specifications.
Although the 194, 192, and 168 share the T10 wedge form factor, their wattage ratings differ: the 194 draws 3.78W, the 192 draws 3W, and the 168 draws 4.9W. These differences mean the bulbs are not direct electrical equivalents despite fitting the same socket type.
The Chevrolet Colorado (2004-2008) uses the 168 bulb for the courtesy application, which at 4.9W carries the highest wattage of any bulb listed across these specifications.
The 192 bulb, used on the Colorado for the 2009-2012 model years, operates at 3W, making it the lowest-wattage bulb referenced in these specifications.
The 12961 Philips bulb, rated at 5W, is specified for the 2015-2016 and 2023 model years. Its wattage is the closest among the listed bulbs to the 168, though the two are not interchangeable designations.
The 2024 Colorado uses the 194 bulb, which operates at 12V and 3.78W, placing it between the 192 and 168 in terms of power draw among the T10 wedge types listed.
Because the specifications reference multiple T10 wedge bulbs with differing wattage ratings across different model years, substituting one T10 bulb for another without matching the specified wattage for a given year risks an incorrect fitment for that application.
