Additional Notes

The 9004 bulb is a dual-filament halogen type operating at 12V with a P29t base and a 65W/45W power rating, where the higher wattage serves the high beam filament and the lower wattage serves the low beam filament. This single bulb handles both functions, which is why the Dodge Colt for 1993-1994 lists the 9004 for both high beam and low beam positions.
The 1992 Dodge Colt headlight configuration varies by the number of headlamps installed. The two-headlamp configuration uses the 9004 dual-filament bulb for both beams, while the four-headlamp configuration splits the functions across two separate single-filament bulbs: the 9005 at 65W for high beam and the 9006 at 55W for low beam.
The 9005 and 9006 bulbs are not interchangeable despite their similar appearance. The 9005 uses a P20d base, while the 9006 uses a P22d base, and their wattage ratings also differ at 65W and 55W respectively.
The H6054, H6024, H5001, and H5006 are all sealed beam units, meaning the lens, reflector, and filament are fused into a single assembly. The entire unit is replaced rather than an internal bulb, and all operate at 12V under the ANSI standard applicable to the US and Canada.
The H6054 is a 5x7-inch rectangular sealed beam unit used on the Colt from 1979-1985, serving both high and low beam positions across those years.
The H6024 is a 7-inch round sealed beam unit, which is a larger format than the H5006's 5.75-inch round unit. The H6024 was fitted to the Colt from 1973-1978 for both beam positions, while the H5001 and H5006 units were used in 1971-1972.
The 1971-1972 Colt used different sealed beam types for each beam function: the H5001, a 4-inch square unit, handled high beam duty, while the H5006, a 5.75-inch round unit, handled low beam duty. These two units are not physically interchangeable due to their differing shapes and sizes.
Across all years in the specifications, every bulb and sealed beam unit listed conforms to ANSI standards recognized in both the US and Canada, indicating consistent regulatory compliance throughout the model's production span covered by these records.
