In the 1980 model year, Toyota released an all-new subcompact car named the Corolla Tercel. In 1983, Toyota completely redesigned the Tercel and dropped "Corolla" from the name. The 1991 model year brought about another complete redesign of the Tercel, as it moved to a more rounded and aerodynamic design. With this redesign came a change of the headlight system, from a sealed beam system to a semi-sealed beam system. Instead of using a large glass headlight, the 1991 Tercel used a plastic assembly with a small, capsule-style bulb inserted into it. Replacing the headlight bulb on the 1991 Tercel's headlight assembly is a task that nearly any do-it-yourself mechanic can complete.
