The Renault Encore high beam headlight bulb size includes H4701 and H4651 options, while low beam headlight bulb size encompasses H4703 and H4652 options. The replacement chart covers 1984 to 1986 vehicle 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 Encore uses four distinct sealed beam unit types across its 1984-1986 model years: H4701, H4651, H4703, and H4652. All four conform to ANSI standards recognized in both the United States and Canada and operate on a 12V electrical system.
Sealed beam units differ from conventional bulbs in that the filament, reflector, and lens are fused into a single glass assembly. When a sealed beam unit fails, the entire unit requires replacement rather than just an internal bulb.
The H4651 and H4703 types are physically distinct from one another. The H4651 is a 4x6-inch rectangular sealed beam unit, while the H4703 is a 7-inch round sealed beam unit. These two formats are not interchangeable.
The H4652, used for the low beam headlight in the 1984-1985 Renault Encore, is described as a variant of the H4651. Both share the 4x6-inch rectangular sealed beam format, though they carry separate ANSI designations reflecting differences in beam pattern or light output.
The H4701, used for the 1986 high beam position, is described as a variant of the 7-inch round sealed beam format. Like the H4652 relative to the H4651, the H4701 and H4703 share the same physical format but are assigned separate designations, indicating they are not direct substitutes for one another.
A format change occurred between the 1985 and 1986 model years. The 1984-1985 Encore used 4x6-inch rectangular sealed beam units for both high and low beam positions, while the 1986 model shifted to 7-inch round sealed beam units for both positions.
Because the high beam and low beam units in each model year follow the same physical format, the round units in 1986 and the rectangular units in 1984-1985 share their respective housing shapes across both beam positions. However, the specific ANSI designations differ between beam positions and must be matched accordingly during replacement.
