Nissan Pickup front side marker bulbs use 194 size while rear side marker bulbs use 158 size. The replacement chart covers 1995 to 1997 model 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 Pickup uses two distinct bulb sizes for its side marker lights across the 1995-1997 model years, with the front and rear positions requiring different specifications.
The front side marker on the 1995-1997 Nissan Pickup takes a 194 bulb, while the rear side marker takes a 158 bulb.
Both the 194 and 158 are ANSI-standardized bulb types recognized in the United States and Canada, meaning they conform to a defined set of electrical and physical standards.
Both bulbs share the T10 miniature wedge form factor, a small, wedge-shaped base design that requires no separate socket retainer and is retained by friction alone.
Both bulbs operate on a 12-volt system, consistent with the standard electrical architecture found in passenger and light commercial vehicles.
The 194 bulb carries a wattage rating of 3.78W, while the 158 bulb is rated at 3W, making the front side marker slightly higher in power consumption than the rear.
Although the 194 and 158 share the same T10 wedge base, their differing wattage ratings mean the two types are not interchangeable without exceeding or underdriving the intended circuit load for each position.
