Patent attributes
Automotive headlight lamps of different kinds have identical burners and upper base parts, but lower base parts of different structures. The upper base part has reference elements, for example, a securing ring, for positioning the lamp at a headlight. The lower base parts vary from one kind of lamp to another, having, for example, different connection devices for electrical contacts. In the lamp manufacturing process, a burner is inserted into an upper base part and, preferably, after having been oriented with respect to a reference element, is fixed in position. Lower base parts including the electrical connection device and having a desired shape are connected with the upper base parts. A two-piece embodiment of the lower base part is also possible, enabling electrical contact elements to be readily accommodated.
