Additional Notes

The Honda CR-V luggage compartment uses two distinct bulb types across its model years: the 168 (T10 wedge) for 2017-2020 and the DE3175 (31mm festoon) for 1997-2012.
Both the 168 and DE3175 are ANSI-standardized bulbs rated for the US and Canadian markets, operating on a 12-volt electrical system.
The 168 bulb is a T10 miniature wedge type, meaning it seats by friction through a wedge-shaped base rather than a bayonet or screw mechanism, and draws 4.9 watts.
The DE3175 is a festoon-style bulb measuring 31mm in length, making contact at both ends through metal end caps rather than a side-mounted base.
The two bulb types are not interchangeable, as the T10 wedge socket and the festoon socket are physically incompatible mounting formats.
The 168 and DE3175 share the same 12-volt operating voltage, though the wattage of the DE3175 is not specified in the provided data.
The DE3175 designation indicates a specific festoon length of 31mm; festoon bulbs of different lengths, such as 28mm or 36mm, would not seat correctly in the same housing.
The T10 designation of the 168 bulb refers to a tubular envelope roughly 10/8 of an inch wide, a standard sizing convention used across many automotive interior applications.
