The Yugo GVX uses 194 bulb size for both front and rear side marker applications. The replacement chart covers 1987 to 1989 vehicle production years with corresponding 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 specified for the Yugo GVX across all listed model years and both front and rear side marker positions.
The 194 bulb is classified as a miniature wedge type, designated T10 in the international bulb nomenclature system.
The T10 wedge base design relies on tension from the socket housing rather than a bayonet or screw mechanism to maintain contact, which is a common trait of low-current marker and courtesy light applications.
The 194 bulb operates at 12 volts with a power draw of 3.78 watts, placing it in the low-wattage category typical of side marker lighting.
The 194 carries ANSI standardization recognized in both the United States and Canada, meaning the specification conforms to a defined performance and dimensional standard rather than a proprietary one.
The front and rear side marker positions on the Yugo GVX (1987-1989) share an identical bulb specification, indicating the same 194 unit is interchangeable between both locations on the vehicle.
Because the 194 is an ANSI-standardized type, aftermarket and OEM replacements from different manufacturers are generally expected to be physically and electrically compatible with the original socket, provided they conform to the same standard.
