It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] A vehicle is generally equipped with interior lighting to provide illumination inside the vehicle cabin. Such interior lighting includes lamp assemblies to provide illumination to a vehicle occupant such that light is produced in low-light conditions.
[0004] In the existing design, lamp assemblies may also have numerous lights or lamps that are used for multiple features. Before being integrated into or mounted onto the vehicle, each lamp assembly is customarily pre-assembled within a protective lamp housing. The entire light assembly is then positioned parallel to the outside surface of the vehicle body, and fastened to it at various points using bolts and other fasteners, such as snap fitting.
[0005] The existing design of lamp assembly includes a lamp housing and a lens that is incorporated inside the lamp housing. The lens has two depressions provided on a left side and a right side. After pressing the left side, the light is switched OFF and if the right side is pressed, the light gets switched ON or vice-versa. The housing has a metal clip and the lens has a plurality of grooves on an extended leg. The groove provide a depth on which the metal clip gets fit.
[0006] Furthermore, in case of resting position or when the switch is OFF, the metal clip stays put on the first groove and in the case as the user switches ON the lamp, the metal clip gets rotated and fits onto a second groove. This feature produces a clicking sound at the attachment point whenever the user presses the switch, thereby producing a noise. The attachment point here is the point of contact between the metal clip and the first and second grooves.
[0007] It is therefore desirable to reduce the noise or the clicking sound that gets generated due to rotating or pressing while switching the lamp ON/OFF .

[0059] It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation, no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to disclosures containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. Also, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general, such construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances, where a convention analogous to “at least one of A, B, or C, etc.” is used, in general, such construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”
