Additional Notes

The T10 miniature wedge form factor is the most prevalent bulb type across the Nissan Maxima courtesy bulb specifications, appearing across the majority of model years covered in the data.
The 194 bulb is an ANSI-standard T10 miniature wedge rated at 12V and 3.78W. It is specified for the Nissan Maxima for the 2004-2008 and 2021-2023 model years.
The 161 bulb is also an ANSI-standard T10 miniature wedge, but it operates at a significantly lower wattage of 1W at 12V. It is specified for the 1995-2002 model years, with the same rating continuing through 1996-2002.
The 158 bulb is an ANSI-standard T10 miniature wedge rated at 12V and 3W, specified for the 1985-1994 model years. Its wattage falls between the 161 and 194 ratings, making direct substitution across these three types inadvisable without confirming socket and circuit compatibility.
The 12961 is a Philips part number rather than an ANSI designation. It shares the T10 wedge form factor with a W2.1x9.5d base and is rated at 12V and 5W, making it the highest-wattage T10 variant in these specifications. It is listed solely for the 2006 Maxima.
Although the 194, 161, 158, and 12961 bulbs all share the T10 wedge form factor, their wattage ratings differ. Substituting one for another may affect circuit load and light output, and the physical fit alone does not confirm electrical interchangeability.
The DE3022 is a festoon-type bulb with a 31mm length and end-cap contacts, a physically distinct format from the wedge-base bulbs used in all other listed years. It is specified for the 1981-1984 Maxima and is not interchangeable with any T10 wedge bulb.
The single model year 1985 uses the 158 wedge bulb, while the immediately preceding years 1981-1984 use the DE3022 festoon type, indicating a change in bulb format between those model years.
