Abstract
A lamp assembly, such as an indicator or illuminator type, has a main body structure detachably securable to an associated support as, for example, an instrument panel of a related vehicle, with such body structure enabling the easy connection thereto of an associated light shield; the body structure carries a separately formed resiliently deflectable detent member enabling easy assembly and disassembly of the shield with respect to the body structure as well as an infinite selection of angular adjustment of the shield relative to body structure.
