Additional Notes

The Toyota Corolla map light specifications reference four distinct bulb types across the listed model years: 194, 168, 12961, and 192. All four share the T10 miniature wedge form factor, meaning they occupy the same physical bulb family despite carrying different part numbers and wattage ratings.
The 192 bulb is an ANSI-standard T10 wedge rated at 12V and 3W, and it appears in the Toyota Corolla across the 2001-2006 model years. At 3W, it draws the least power of any bulb type listed in these specifications.
The 194 bulb is also an ANSI-standard T10 wedge but is rated at 12V and 3.78W. It is specified for the 2023-2024 Corolla map light position.
The 168 bulb is an ANSI-standard T10 wedge rated at 12V and 4.9W, making it the highest-wattage option among the listed types. For the 2014-2016 Corolla, this bulb applies specifically to vehicles equipped with a moonroof, indicating a trim-level or package dependency for those years.
The 12961 is a Philips part number rather than an ANSI industry code. It designates a T10 wedge bulb with a W2.1x9.5d base, rated at 12V and 5W, and is specified for the 2009-2013 Corolla map light.
Because the 192, 194, and 168 bulbs all carry ANSI designations while the 12961 is a manufacturer-specific part number, the two classification systems are not directly interchangeable references even though the underlying bulb construction is similar.
Although the 194 and 168 bulbs share the same T10 wedge base and both operate at 12V, their wattage ratings differ by more than one watt. Substituting one for the other would alter the power draw at the socket, which is a relevant fitment consideration for the 2020 and 2023-2024 model years where each is separately specified.
The moonroof condition noted for the Toyota Corolla in 2014-2016 suggests that vehicles without that feature may use a different bulb size for the map light position in those years, as the specification is explicitly conditional on that equipment.
