Nissan Van high beam and low beam headlight bulbs both utilize a 9004 bulb size. The replacement chart covers vehicle production spanning 1987 to 1988.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9004 is a dual-filament halogen bulb operating at 12 volts, with a high beam output of 65 watts and a low beam output of 45 watts. Its base type is P29t, a three-contact connector that carries separate circuits for each filament.
Because the 9004 serves both filaments within a single bulb, the Nissan Van (1987-1988) uses the same part number for both the high beam and low beam positions rather than separate bulbs for each function.
The 9004 designation follows ANSI standardization, meaning the bulb specification is recognized across the United States and Canada under a uniform technical definition.
The P29t base is not interchangeable with other common halogen base types such as H4 or 9007, as each uses a distinct connector configuration and pin arrangement. Substituting an incompatible base type would prevent proper seating in the headlight housing.
The 9007 bulb is sometimes confused with the 9004 due to similar wattage ratings, but the two differ in their connector key positions, making them physically non-interchangeable despite outward resemblance.
