The MG TD headlight bulb uses a H6024 size for both high and low beam functions. The replacement chart covers 1950 to 1953 production years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The H6024 is the sole bulb type listed across all positions in the MG TD headlight specifications, appearing in both the high beam and low beam roles for the 1950-1953 model years.
The H6024 is a 7-inch round sealed beam unit operating at 12 volts, conforming to ANSI standards recognized in the United States and Canada.
As a sealed beam unit, the H6024 is a self-contained assembly in which the lens, reflector, and filament form a single sealed housing. When the filament fails, the entire unit is replaced rather than an individual bulb.
The high beam and low beam positions on the MG TD share the same H6024 specification across all listed years, indicating that a single unit type serves both functions.
The 7-inch round format of the H6024 is a standardized sealed beam size, meaning units from different manufacturers conforming to that standard are generally interchangeable at the socket and mounting level.
