The Dodge Omni uses H6054 bulb size for both high beam and low beam headlight applications. The replacement chart covers vehicle production spanning 1978 to 1990.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The H6054 is the sole headlight bulb size specified for the Dodge Omni across all model years from 1978-1990, covering both high beam and low beam functions.
The H6054 is a 5x7-inch rectangular sealed beam unit operating at 12 volts, conforming to ANSI standards recognized in both the United States and Canada.
A sealed beam unit integrates the filament, reflector, and lens into a single glass housing, meaning the entire assembly is replaced rather than an internal bulb component.
The same H6054 unit serves both the high beam and low beam positions on the Dodge Omni, indicating the vehicle uses a dual-filament sealed beam design rather than separate housings for each function.
Because the H6054 follows an ANSI standardized form factor, units produced by different manufacturers are generally interchangeable as long as they conform to the same standard designation.
The consistent use of the H6054 across the entire 1978-1990 production span of the Dodge Omni means no year-specific fitment distinctions exist within this model line for headlight bulbs.
