The MG Midget uses H6024 bulb size for both high beam and low beam headlight applications. The replacement chart covers 1969 to 1979 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.
The MG Midget uses the H6024 bulb size for both high beam and low beam headlights across the 1969-1979 model years.
The H6024 is a sealed beam unit, meaning the lens, reflector, and filament are fused into a single assembly. When the filament fails, the entire unit is replaced rather than an internal bulb.
The H6024 follows the ANSI standard format recognized in the United States and Canada, specifying a 7-inch round sealed beam configuration operating at 12 volts.
Because the MG Midget uses the same H6024 unit for both high and low beam functions, the headlight assembly serves a dual-beam role within one sealed unit rather than relying on separate bulbs for each function.
The consistent use of a single bulb size across both beam types and all listed model years indicates that the headlight housing design remained unchanged throughout the 1969-1979 production span.
The 7-inch round sealed beam format was a widely standardized size in North American automotive lighting regulations during this period, which means H6024-compatible units were produced by multiple manufacturers and are broadly interchangeable at the hardware level, provided the voltage rating of 12V is matched.
