The Yugo GV uses the 194 bulb for both front and rear side markers across all listed model years, spanning 1986-1992.
The 194 is an ANSI-standardized bulb type, meaning its specifications are governed by a formal industry standard recognized across the United States and Canada.
This bulb belongs to the T10 miniature wedge family, a form factor defined by its wedge-shaped base, which seats directly into a socket without a separate metal cap or bayonet pins.
The 194 operates at 12 volts, consistent with the standard electrical system voltage found in conventional passenger vehicles of this era.
At 3.78 watts, the 194 draws relatively low power, which is typical for side marker applications where continuous illumination is required without significant electrical load.
Because the front and rear side marker positions on the Yugo GV share the same bulb size, a single 194 bulb serves as a direct fitment for all four side marker sockets on the vehicle.
The T10 wedge base format is widely produced and used across many vehicle makes, which means the 194 is not an application-exclusive bulb specific to the Yugo GV.
Substitution with bulbs of a different wattage or base type would not conform to the original socket and circuit specifications, as the 194 designation defines both the physical form factor and the electrical rating together.
