The Simca 1118 uses H6024 bulb size for both high beam and low beam headlight applications. The replacement chart covers 1969 to 1971 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 H6024 is the sole bulb type listed across all headlight positions for the Simca 1118, covering the 1969-1971 model years.
The H6024 is a 7-inch round sealed beam unit operating at 12 volts, built to ANSI standards for the US and Canadian markets.
A sealed beam unit integrates the filament, reflector, and lens into a single fused glass assembly, meaning the entire unit is replaced rather than an internal bulb.
The Simca 1118 uses the same H6024 specification for both high beam and low beam functions, indicating a dual-filament sealed beam design within one unit.
The H6024 designation follows ANSI standardization, which means the unit is interchangeable with any other H6024-rated sealed beam regardless of manufacturer.
The 7-inch round form factor of the H6024 was a widely adopted standard in North American automotive lighting regulations during this era, making replacement units broadly available across multiple brands.
