Toyota Land Cruiser Courtesy Bulb Size

Additional Notes

• The Toyota Land Cruiser courtesy bulb specifications cover model years 1988-2015, with three distinct bulb types appearing across that span: the 168, 194, and two festoon variants, DE3022 and DE3175.
• The 168 bulb is the most frequently specified type across the listed years, appearing in the 1998-2002 range, the 2008-2011 range, and the 2014-2015 entries. It is a T10 miniature wedge bulb rated at 12V and 4.9W, conforming to the ANSI standard used in the US and Canada.
• The 194 bulb shares the same T10 miniature wedge form factor as the 168 but draws less power at 3.78W versus 4.9W. Despite this physical similarity, the two are not the same specification, and the Toyota Land Cruiser (2003-2007) is listed with the 194 rather than the 168.
• Because the 168 and 194 share the T10 wedge base, they are physically interchangeable in many sockets, but their wattage difference means substituting one for the other results in a change in light output. The specifications list them as distinct requirements for different model years.
• The DE3022 and DE3175 are both 31mm festoon bulbs operating at 12V with end-cap contacts, conforming to the ANSI standard. Festoon bulbs seat into spring-clip holders rather than wedge sockets, making them incompatible with the T10 wedge fittings used in later years.
• The Land Cruiser (1994-1997) uses the DE3022, while the 1988-1993 model years use the DE3175. Both share the 31mm length, and the two designations reflect differences in internal construction rather than external form, so confirming the exact type before replacement is relevant.
• The 2015 model year carries a production date qualifier, specifying the 168 bulb only for vehicles produced up to August 2015. This indicates a mid-year specification change for that model year.
• A gap exists in the listed data for the 2012 model year, and no bulb size is recorded for it in the specifications provided.
