Operation Light was a British naval operation in World War II under the command of Rear Admiral Clement Moody. The objective was to carry out aerial strikes on Japanese positions in Sigli, Northern Sumatra, Indonesia, and aerial reconnaissance over the Nicobar Islands, from 16–23 September 1944. The operation was scheduled to coincide with the Allied landing at Morotai, designated Operation Tradewind, as well as the U.S. 1st Marine Division's landing at Peleliu.
