Honda Pilot Luggage Compartment Bulb Size

Additional Notes

• The Honda Pilot luggage compartment uses three distinct bulb types across its model years: the 168, DE3175, and DE3022, all of which conform to ANSI standards recognized in the United States and Canada.
• The 168 bulb is a T10 miniature wedge type rated at 12V and 4.9W. The wedge base design means the bulb is held in place by the socket itself rather than by pins or caps, and no separate base is attached.
• The DE3175 and DE3022 are both festoon-style bulbs with a 31mm length and end-cap contacts. In a festoon configuration, the bulb bridges two spring-loaded contacts at either end of the housing rather than inserting into a socket from below.
• The Honda Pilot (2019-2020) uses the 168 wedge bulb for the luggage compartment.
• Model years 2009-2015 use the DE3175 festoon bulb, making it the most consistently specified type across the listed data for this vehicle.
• The 2003-2007 Pilot uses the DE3022 festoon bulb. Although the DE3022 and DE3175 share the same 31mm length and end-cap contact design, they carry different ANSI designations and are not confirmed as interchangeable by these specifications.
• The shift from the DE3022 to the DE3175 between the 2007 and 2009 model years, and from the DE3175 to the 168 wedge between 2015 and 2019, reflects changes in socket type across generations, meaning bulbs from one generation are not physically compatible with sockets from another.
• All three bulb types operate on a 12V circuit, consistent with standard automotive electrical systems.
• The 168 wedge bulb carries an explicit 4.9W rating in the specifications. The DE3175 and DE3022 listings state only the voltage, with no wattage value provided for either festoon type.
• Because the DE3022 and DE3175 share physical characteristics but hold separate ANSI designations, substituting one for the other without confirming socket and electrical compatibility with the specific model year is not supported by these specifications.
