The Mercedes-Benz 300TE uses 9004 bulb size for both high beam and low beam headlight applications. The replacement chart covers vehicle production years spanning 1988 to 1993.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9004 bulb is the sole bulb type specified across all headlight positions for the Mercedes-Benz 300TE, covering both high beam and low beam functions for the 1988-1993 model years.
The 9004 is a dual-filament halogen bulb, meaning a single unit contains two separate filaments: one rated at 65 watts for high beam output and one rated at 45 watts for low beam output.
Because both the high beam and low beam positions share the same 9004 specification, a single bulb type serves both lighting functions rather than requiring separate bulbs for each.
The 9004 operates on a 12-volt electrical system, which is standard for passenger vehicles of this type.
The 9004 uses a P29t base, a specific connector configuration that is not interchangeable with other common halogen base types such as H4 or 9007, despite those bulbs also using a dual-filament design.
The 9004 is an ANSI-standardized bulb recognized in the United States and Canada, meaning its electrical and physical specifications conform to a defined North American standard.
The 9007 bulb shares a similar wattage profile with the 9004 but uses a different base orientation, making the two types physically incompatible despite their comparable output ratings.
