Toyota Camry Courtesy Bulb Size

Additional Notes

• The Toyota Camry courtesy bulb specifications reference three distinct bulb families across the model's history: miniature wedge bulbs (T10 format), festoon bulbs with end-cap contacts, and a halogen specialty bulb. Each family uses a different physical mounting method, making cross-family substitution incompatible.
• The 168 bulb is the most frequently specified courtesy bulb across the Camry's listed model years, covering 2012-2019 and 2023-2024. It is an ANSI-standard T10 miniature wedge bulb rated at 12V and 4.9W, with the wedge base serving as both the electrical contact and the mechanical retention point.
• The 12961 bulb, specified for the 2021-2022 Camry, is a Philips part number rather than an ANSI designation. It shares the T10 wedge format and W2.1x9.5d base with the 168 bulb but is rated at 5W rather than 4.9W. Despite the near-identical physical format, the differing part number origin means fitment should not be assumed interchangeable without verification.
• The 194 bulb, listed for the 1994-1995 Camry, is also an ANSI T10 miniature wedge type but is rated at 3.78W, noticeably lower than both the 168 and 12961 bulbs. All three T10 wedge types operate at 12V, yet their wattage differences reflect distinct filament specifications.
• Festoon bulbs appear across several non-consecutive model years. The DE3022 is specified for the 1985-1991 Camry, while the DE3021 covers 1997 and 2001, and the DE3175 covers 1999-2000. All three are ANSI-standard festoon bulbs with a 31mm length and end-cap contacts operating at 12V, though they carry separate designations and are not confirmed as interchangeable.
• The 13050 bulb, listed for the 1993, 1996, and 1998 Camry, is identified as an OEM/Wagner part number for a halogen specialty application at 12V. Its classification under a manufacturer-specific part number rather than an ANSI code indicates it does not share a standardized cross-reference designation with the other bulb types in these specifications.
• The courtesy bulb specification for the Toyota Camry changes across certain model year boundaries, including between 2019 and 2021, and between 2022 and 2023. These transitions involve shifts between bulb types or part number origins, meaning a bulb correct for one year may not be the specified fitment for an adjacent year.
• The festoon bulbs in these specifications (DE3021, DE3022, and DE3175) all share the same 31mm length and end-cap contact design. However, because they carry distinct ANSI designations, they are treated as separate specifications, and the data does not confirm that one can serve as a direct replacement for another.
