The Renault R17 uses a 89 bulb size for both front and rear side marker positions. The replacement chart covers 1972 to 1979 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 Renault R17 uses the 89 bulb for both front and rear side markers across all model years covered in the specifications, spanning 1972-1979.
The 89 is an ANSI-standard bulb recognized in the United States and Canada, operating at 12 volts and 13 watts.
It is a single-filament bulb, meaning it serves one lighting function rather than combining two, such as running and braking, into a single unit.
The 89 uses a BA15s bayonet base, a single-contact mount where the bulb locks into its socket with a twist rather than a threaded connection.
The 89 is a lower-wattage variant of the 1156 bulb, which shares the same BA15s bayonet base but draws more power, making the two types electrically incompatible as direct replacements despite their physical similarities.
Because the Renault R17 (1972-1979) specifies the 89 rather than the 1156 for side marker positions, substituting a 1156 would introduce a higher wattage draw than the circuit was designed to handle.
The front and rear side marker positions on the R17 share the same bulb specification throughout the entire 1972-1979 production range, indicating no positional distinction in the lighting requirement between the two locations.
