Nissan 200SX front and rear side marker bulb sizes include 194, 67, 158, and 97 configurations across different model generations. The replacement chart covers 1977 to 1988 production years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Nissan 200SX front side marker uses the 194 bulb for the 1984-1988 model years. The 194 is a T10 miniature wedge bulb rated at 12V and 3.78W, standardized under ANSI specifications for the US and Canadian markets.
The 158 bulb shares the same T10 miniature wedge form factor as the 194 but draws slightly less power at 3W versus 3.78W. On the Nissan 200SX, the 158 serves as the rear side marker for the 1984-1988 model years, as well as both front and rear side markers for the 1980-1981 model years.
Because the 194 and 158 are both T10 wedge bulbs, they share a physically compatible base. However, their wattage ratings differ, and substituting one for the other may not meet original equipment specifications.
The 67 bulb is a single-filament type with a BA15s bayonet base, rated at 12V and 8W. It is described as a lower wattage variant of the 1156. On the 200SX, it appears in both front and rear side marker positions for the 1982-1983 and 1979 model years.
The 97 bulb also uses a BA15s bayonet base and is rated at 12V and 13W, making it a higher wattage variant within the same 1156 family as the 67. The 200SX uses the 97 in both front and rear side marker positions for the 1977-1978 model years.
The 67 and 97 bulbs share the same BA15s bayonet base style but carry different wattage ratings of 8W and 13W respectively. Physical interchangeability does not indicate electrical equivalence between these two types.
All four bulb types used across the 200SX side marker positions conform to ANSI standards applicable in both the United States and Canada.
The 200SX side marker specifications reflect two distinct base technologies across its model range: the T10 wedge base, used by the 194 and 158, and the BA15s bayonet base, used by the 67 and 97. These two base types are not interchangeable with one another.
