The 1157 is the bulb type specified for both the front and rear turn signals of the Yugo Cabrio across the 1990-1992 model years.
The 1157 is a dual-filament bulb, meaning it contains two separate filaments within a single envelope, allowing it to serve two distinct lighting functions at different wattages.
The 1157 operates on a 12-volt electrical system and draws 21 watts on its primary filament and 5 watts on its secondary filament.
The 1157 uses a BAY15d bayonet base, which features two offset pins at different heights to ensure correct orientation during installation and prevent incorrect seating.
The 1157 is classified under the ANSI standard and is recognized across the United States and Canada under that designation.
Because the same bulb type is specified for both the front and rear turn signal positions, the 1157 is interchangeable between those two locations on the Yugo Cabrio.
