The Renault R16 front and rear turn signal bulbs both utilize a 1157 bulb size for proper operation. The replacement chart covers 1969 through 1972 production years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 1157 is the sole bulb type specified for the Renault R16 across all listed positions and years, covering both the front and rear turn signals from 1969-1972.
The 1157 is an ANSI-standardized bulb, meaning its physical and electrical characteristics conform to a defined North American specification used in the United States and Canada.
The 1157 is a dual-filament bulb, which means it contains two separate filaments within a single envelope, allowing it to serve two distinct lighting functions from one unit.
The 1157 uses a BAY15d bayonet base, a two-pin offset base design where the two pins are positioned at different heights to prevent incorrect insertion orientation.
The 1157 operates at 12 volts, consistent with the standard automotive electrical system voltage of the era.
The two filaments in the 1157 are rated at 21 watts and 5 watts respectively, with the higher-wattage filament typically serving the turn signal function and the lower-wattage filament serving a secondary function such as a parking or tail light.
Because the 1157 serves both the front and rear turn signal positions on the Renault R16 (1969-1972), the same bulb type is interchangeable between those two locations on the vehicle.
