The Nissan 280ZX headlight bulb uses an H6024 size for both high beam and low beam applications. The replacement chart covers vehicle production spanning 1979 to 1983.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The H6024 is the sole bulb type specified across all headlight positions on the Nissan 280ZX for the 1979-1983 model years, covering both high beam and low beam functions.
The H6024 is a 7-inch round sealed beam unit operating at 12 volts. It conforms to ANSI standards applicable in the United States and Canada.
A sealed beam unit integrates the filament, reflector, and lens into a single fused glass assembly. Because these components are not separable, the entire unit is replaced rather than an internal bulb alone.
The H6024 serves dual duty on the Nissan 280ZX, fulfilling both the high beam and low beam headlight positions. This is consistent with sealed beam designs of that era, where a single unit could house multiple filaments to produce both light modes.
The uniform fitment of the H6024 across all five model years and both beam positions means that no year-specific or position-specific variation exists within this application range, simplifying parts interchangeability across the 1979-1983 production span.
