Renault R15 front and rear side marker bulbs utilize an 89 bulb size for both locations. The replacement chart covers vehicle production spanning 1974 to 1976.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Renault R15 uses the 89 bulb for both front and rear side marker positions across the 1974-1976 model years.
The 89 is an ANSI-standard bulb recognized in the US and Canadian markets, operating at 12 volts and 13 watts.
It uses a BA15s bayonet base, which is a single-contact fitting where the pin is centered and the bulb locks into the socket with a push-and-twist motion.
The single-filament design of the 89 means it serves one lighting function only, as opposed to dual-filament bulbs that handle two functions such as running and braking from a single unit.
The 89 is a lower wattage variant of the 1156 bulb. Both share the BA15s base, but the 1156 operates at a higher wattage, making the two non-equivalent as direct replacements despite their physical similarity.
The shared bulb type across all six positions, front and rear on both sides for all three model years, indicates a uniform fitment throughout the Renault R15 side marker system for this production period.
