Mercedes-Benz 190E Headlight Bulb Size

The Mercedes-Benz 190E high and low beam headlight bulbs utilize a 9004 or H6054 size. The replacement chart covers 1984 to 1993 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.

Additional Notes

The 9004 is a dual-filament halogen bulb, meaning a single unit contains two filaments: one rated at 65W for high beam and one at 45W for low beam. It operates at 12V and uses a P29t base.
Because the 9004 handles both high and low beam functions within one bulb, the Mercedes-Benz 190E from 1987-1993 uses the same part number across both headlight positions rather than separate bulbs for each function.
The H6054 is a 5x7-inch rectangular sealed beam unit rather than a replaceable bulb. When the light fails, the entire housing assembly is replaced as a single component.
The 190E used the H6054 sealed beam unit for both high and low beam headlights during the 1984-1986 model years, following the same dual-position pattern seen in the later 9004 configuration.
The 9004 bulb conforms to ANSI standards applicable in the United States and Canada, as does the H6054, placing both types within the same regulatory framework despite their fundamentally different constructions.
The transition from the H6054 sealed beam to the 9004 halogen bulb occurred between the 1986 and 1987 model years on the Mercedes-Benz 190E, representing a shift from a fixed sealed unit to a replaceable filament-based design.
The P29t base on the 9004 bulb is a specific connector type, and substituting a bulb with a different base would require an adapter or would be physically incompatible with the socket.
