Nissan Altima Glove Box Bulb Size

Additional Notes

• The Nissan Altima glove box uses two distinct bulb types across its model years: the 158 and the 74, both of which are ANSI-standardized miniature wedge bulbs rated for 12-volt electrical systems.
• The 158 bulb is a T10 wedge type rated at 3 watts, while the 74 is a smaller T5 wedge type rated at 1.4 watts. These two bulb families are not interchangeable due to differences in physical size and wattage.
• The Nissan Altima (2014-2018) uses the 74 bulb for the glove box, with 2014-2017 sharing the same T5 specification.
• Model years 2019-2024 return to the 158 T10 bulb, which is also the bulb type found in the 1995-1999, 2005-2006, and 2009 model years.
• The T5 designation on the 74 bulb refers to a tubular envelope that is 5/8 of an inch wide, making it noticeably narrower than the T10 envelope of the 158 bulb, which spans 10/8 of an inch in width.
• Both bulb types use a wedge base, meaning the electrical contacts are formed by the glass envelope itself rather than a separate metal base, which is a common construction for low-wattage interior lighting applications.
• The wattage difference between the two bulb types is significant in relative terms: the 158 draws more than twice the power of the 74, reflecting the larger filament housed within the T10 envelope.
