The clip comes from T-Bone for Two, a Pluto cartoon released on 14 August 1942, during the classic era of hand-drawn Disney shorts. The bulb horn belongs to that period of cartoon sound design, when squeaky, exaggerated effects did much of the comic work without dialogue. Long after its original screening, the short burst survived in sound libraries such as the Hollywood Edge collection, where editors could reuse it for cartoons, comedies and short online videos. Its age is part of its charm, instantly signalling an old-fashioned gag.
