The Renault R15 high beam headlight uses an H5001 bulb size while the low beam headlight requires an H5006 bulb size. The replacement chart covers 1974 to 1976 production years with corresponding bulb size specifications.
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 H5001 sealed beam unit for high beam headlights across the 1974-1976 model years, and the H5006 sealed beam unit for low beam headlights across the same period.
Both the H5001 and H5006 are ANSI-standardized sealed beam units, a format governed by North American (US and Canada) specifications that defines the physical and electrical characteristics of the lamp as a fixed assembly.
The H5001 is a 4-inch square sealed beam unit operating at 12 volts. Because the light source is fused permanently into the reflector and lens as a single assembly, the entire unit is replaced rather than an internal filament or capsule.
The H5006 is a 5.75-inch round sealed beam unit, also rated at 12 volts and also replaced as a complete assembly. Its round form factor distinguishes it physically from the square H5001 used on the high beam position.
The square profile of the H5001 and the round profile of the H5006 mean the two units are not interchangeable, as their housings and mounting configurations correspond to different headlight positions on the vehicle.
The ANSI standardization of both bulb types means that replacement units sourced from different manufacturers are expected to conform to the same physical and electrical specifications, provided they carry the correct H5001 or H5006 designation.
