Subsequent Events [Text Block]	Note 11 – Subsequent Events On June 25, 2015, the Company filed a registration statement (as subsequently amended on July 31, 2015, August 7, 2015, August 19, 2015 and September 15, 2015) relating to a rights offering of Series B Convertible Preferred Stock intended to raise up to $10.2 million before expenses. The registration statement was declared effective by the SEC on September 24, 2015. The rights offering commenced on October 14, 2015 and expires on November 19, 2015 (extended from the original expiration date of November 4, 2015). The Company intends to use the net proceeds for repayment of debt, required pension plan payments and for general corporate purposes. Under the terms of the rights offering, the Company distributed one non-transferrable right for each outstanding share of Common Stock to stockholders of record on September 28, 2015. Thirty-three non-transferable rights entitle the holder to purchase one share of Series B Convertible Preferred Stock at a subscription price of $20.00 per share. The Series B Convertible Preferred Stock carries a 6.0% cumulative annual dividend and is convertible into shares of Common Stock at an initial conversion price of $10.00 per share, representing a conversion ratio of 20 shares of Common Stock for each share of Series B Convertible Preferred Stock held at the time of conversion, subject to adjustment. The shares of Series B Convertible Preferred Stock may be subject to mandatory conversion after three years, or as early as one year if the closing sale price of the Common Stock has been greater than or equal to $15.00 for 30 consecutive trading days. There can be no assurance as to the amount that the Company will raise in the rights offering. This Quarterly Report on Form 10-Q does not constitute an offer to sell, or the solicitation of an offer to buy, any securities, and there will be no sale of any securities in any state in which such an offer, solicitation, or purchase would be unlawful prior to the registration or qualification of such securities under the securities laws of any such state. The offer of the shares of Series B Convertible Preferred Stock issuable upon exercise of the rights is made only by means of the prospectus dated October 14, 2015 forming a part of Trans-Lux’s registration statement filed with and declared effective by the SEC, and related documents.
