The Dodge Rampage high beam and low beam headlight bulb sizes include H4651, H6054, and H4656 options, with each bulb size corresponding to specific lighting functions. The replacement chart covers 1982 to 1984 model years and details bulb size specifications across the vehicle production range.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Dodge Rampage uses two distinct sealed beam sizes across its headlight specifications: the 4x6-inch rectangular format, designated by H4651 and H4656, and the larger 5x7-inch rectangular format, designated by H6054.
All three bulb types, H4651, H4656, and H6054, are sealed beam units operating at 12V and conforming to ANSI standards recognized in both the United States and Canada.
Sealed beam units are self-contained assemblies in which the filament, reflector, and lens are fused into a single housing, meaning the entire unit requires replacement rather than an internal bulb.
The 1982-1983 Rampage uses the H6054 for both high beam and low beam positions, making the same 5x7-inch sealed beam unit serve dual functions across both headlight roles.
The 1984 Rampage departs from this arrangement, with the high beam position using the H4651 and the low beam position using the H4656, both of which share the 4x6-inch rectangular format.
Although the H4651 and H4656 share the same physical 4x6-inch sealed beam format, they carry different ANSI designations and are assigned to separate beam positions, indicating they are not interchangeable despite their identical housing size.
