Austin Healey 3000 headlight bulbs utilize the H6024 size for both high and low beam functions. The replacement chart covers vehicle production spanning 1959 to 1967 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 H6024 is the sole bulb type specified across all headlight positions for the Austin Healey 3000, covering every model year from 1959 to 1967.
The H6024 is a 7-inch round sealed beam unit operating at 12 volts, conforming to ANSI standards applicable in the United States and Canada.
A sealed beam unit integrates the filament, reflector, and lens into a single fused glass assembly, meaning the entire unit is replaced rather than an internal bulb.
The H6024 serves both the high beam and low beam headlight positions across the full 1959-1967 production span, indicating a single-unit design handles both functions.
Because both beam functions share the same H6024 specification, no separate bulb type is required for high or low beam service on this vehicle.
The ANSI designation of the H6024 places it within a standardized North American sizing system, which historically allowed interchangeability across vehicles specifying the same sealed beam code.
