Additional Notes

The Honda CR-V map light specifications reference three distinct bulb types across the model's history: the 12961, DE3175, and DE3022.
The 12961 is a Philips part number designating a T10 miniature wedge bulb with a W2.1x9.5d base, rated at 12V and 5W. It fits the Honda CR-V map light position for the 2002-2006 and 2013-2022 model years.
The T10 wedge base design means the bulb is held in place by friction against the socket walls rather than by a bayonet or screw mechanism, which is a common trait in interior lighting applications.
The DE3175 and DE3022 are both ANSI-standard festoon bulbs with a 31mm length and end-cap contacts, operating at 12V. Festoon bulbs make electrical contact at each end of the cylindrical body rather than through a base pin or wedge.
Although the DE3175 and DE3022 share the same physical 31mm length and end-cap contact style, they carry different ANSI designations, which can indicate differences in wattage or filament construction. These two types are not confirmed interchangeable by the specifications.
The DE3022 is specified for the Honda CR-V map light across the 1997-2001 model years, while the DE3175 applies to the 2007-2012 model years.
The 12961 wedge-type bulb and the DE3175 or DE3022 festoon-type bulbs use fundamentally different socket designs and are not physically interchangeable with one another.
Selecting a bulb by type name alone, without confirming the specific ANSI or manufacturer designation, risks installing an incompatible part, particularly given that festoon bulbs of the same length can carry different electrical ratings.
