Additional Notes

The Toyota RAV4 trunk bulb specifications reference four distinct bulb types across model years 1996-2024: the 194, 12961, DE3423, and DE3175.
The 194 and 12961 are both T10 miniature wedge bulbs operating at 12V, though they differ in wattage. The 194 draws 3.78W, while the 12961 draws 5W.
The 12961 is a Philips part number rather than an ANSI standard designation, and it uses a W2.1x9.5d base, which is the standard base type for T10 wedge bulbs.
Although the 194 and 12961 share the same T10 wedge form factor, their wattage difference means they are not confirmed interchangeable in these specifications. The RAV4 uses the 194 for 2022-2024 and the 12961 for 2015-2018.
The DE3423 and DE3175 are both festoon-type bulbs, which seat horizontally between two spring-loaded end-cap contacts rather than using a wedge or pin base. Both operate at 12V.
The key physical difference between the two festoon types is length. The DE3423 is 41mm long, and the DE3175 is 31mm long. These two bulbs are not interchangeable due to this size difference.
The DE3175 is the trunk bulb for the Toyota RAV4 across model years 1996-2005, making it the longest-running single bulb type in these specifications.
The DE3423 applies to RAV4 model years 2006-2011, representing a change from the shorter 31mm festoon to the longer 41mm festoon format.
The 194 and 12961 are both ANSI-classified or manufacturer-designated wedge bulbs, representing a shift away from festoon-style fitment in the RAV4 trunk from 2015 onward.
All four bulb types in these specifications operate on a 12V system, consistent with standard automotive electrical architecture.
