Danger Lights

Danger Lights is a well-documented public domain film. It was produced by RKO Radio Pictures and originally registered for copyright on October 25, 1930, under registration number LP1734. Under the terms of the Copyright Act of 1909, the original term of copyright was 28 years, requiring a renewal filing in the 28th year to extend protection. A search of the Stanford Copyright Renewal Database and the Library of Congress Catalog of Copyright Entries (CCE) reveals that no renewal was ever filed for this title by RKO or its successors (such as General Tire or United Artists). Because the copyright was not renewed in 1957 or 1958, the film entered the public domain in the United States upon the expiration of its first term. The film is widely available on public domain archival sites and has been released by numerous budget home video labels specializing in PD content, such as Alpha Video.
