Daihatsu Rocky front and rear side marker bulbs use 194 size bulbs for both positions. The replacement chart covers 1990 to 1992 production years with bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 194 bulb is the sole bulb type across all side marker positions on the Daihatsu Rocky for the 1990-1992 model years.
The 194 is a miniature wedge-base bulb, classified under the T10 form factor, which refers to its tubular shape with a width of approximately 10 millimeters.
The 194 operates at 12 volts with a power draw of 3.78 watts, placing it in the low-wattage range typical of marker and courtesy lighting applications.
The 194 carries ANSI standardization recognized in both the United States and Canada, meaning it conforms to a defined set of electrical and physical tolerances shared across compliant manufacturers.
The wedge base design of the 194 means the bulb is held in its socket by the tension of the base contacts rather than by a bayonet or screw mechanism, which is a common trait in small marker light housings.
The front and rear side marker positions on the Daihatsu Rocky (1990-1992) share the same 194 bulb specification, indicating physical and electrical interchangeability between those two positions.
Because the T10 wedge base is a widely produced form factor, the 194 is available from numerous manufacturers, though voltage and wattage ratings must match the 12V, 3.78W specification to ensure proper function.
