In 1968, the Jaguar E-Type underwent significant changes due to upcoming US emissions and safety regulations. One notable design alteration was the replacement of glass-covered headlamps with raised, chrome-rimmed open units.
During the transition at the Coventry factory, a limited number of late Series 1 E-Types were equipped with open headlight body panels intended for the Series 2 cars. These models, informally referred to as “Series 1.25” and later “Series 1.5” by Jaguar enthusiasts, retained the qualities of the previous generation while adopting the updated appearance of the new generation.
