The Renault LeCar high beam and low beam headlight bulbs utilize H6054 and H6024 bulb sizes for optimal illumination. The replacement chart covers vehicle production years spanning 1977 to 1983 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 LeCar used two distinct sealed beam headlight types across its production run: the H6024 for 1977-1980 models and the H6054 for 1981-1983 models.
Both the H6024 and H6054 are ANSI-standardized sealed beam units recognized in the United States and Canada, operating at 12 volts.
The H6024 is a 7-inch round sealed beam unit, while the H6054 is a 5x7-inch rectangular sealed beam unit. The two formats are physically incompatible with each other due to their differing shapes and housing requirements.
Sealed beam units are self-contained assemblies in which the filament, reflector, and lens are fused into a single glass envelope. When the filament fails, the entire unit is replaced rather than an individual bulb.
On the Renault LeCar, the same bulb type serves both the high beam and low beam functions for any given model year, meaning a single sealed beam unit handles both lighting modes through separate filaments within the assembly.
The transition from the round H6024 to the rectangular H6054 occurred between the 1980 and 1981 model years, representing a change in headlight housing geometry that affects direct part interchangeability between those two production periods.
