Jeep Willys headlight bulbs utilize H6024 and H6006 sizes for both high and low beam applications, with these bulb designations representing the specific specifications required for this vehicle model. The replacement chart covers 1950 to 1958 production years and details the bulb size specifications across the entire range of those years.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The H6006 is a 5x7-inch rectangular sealed beam unit operating at 12V and conforming to ANSI standards recognized in the US and Canada. As a sealed beam design, the entire unit is replaced rather than an internal filament or capsule.
The H6024 is a 7-inch round sealed beam unit, also rated at 12V and built to the same ANSI standard. Like the H6006, it requires full unit replacement when it fails.
The Jeep Willys used the H6006 for both high beam and low beam headlights across the 1950-1957 model years. A single bulb type serving both beam functions is characteristic of older sealed beam systems, where the beam pattern is fixed within the unit itself.
The 1958 Jeep Willys represents a departure from the H6006, with the H6024 specified for both the high beam and low beam positions. The shift from a rectangular to a round sealed beam format reflects a distinct fitment change for that model year.
Because the H6006 and H6024 differ in both shape and physical size, the two types are not interchangeable. Installing the wrong sealed beam unit would result in an improper fit within the headlight housing.
Sealed beam headlights of this era integrate the lens, reflector, and filament into a single glass unit. This construction was the prevailing headlight standard in North American vehicles during the period covered by these specifications.
