Lights Out: Oxychloride X (1943) | Chemical Horror Returns Radio
The formula has escaped again. Lights Out returns to its most viscerally disturbing chemical horror — a compound that dissolves organic matter on contact — in a second telling that has learned from the first that containment is an illusion. Originally broadcast February 16, 1943. This recording is in the Public Domain in the United States. Vintage Chills • Classic Serials • AI-Generated Terror

About Lights Out
Lights Out was one of radio’s first and most daring horror programs, premiering on NBC Radio in 1934. Created by Wyllis Cooper and later shaped by Arch Oboler, the show ran until 1947 and became infamous for episodes so disturbing NBC received thousands of complaints — and renewed it anyway. The sound design pushed the medium to its absolute limits.
