Other stories on the origin of the name include a story that Colton was lighting a Searchlight brand of matches when he discovered the gold ore. Reid dismisses this story saying that the Searchlight matches were not available in 1898. Yet another story says that Colton thought the area would be a good place because it was on a hill. Colton's mine was called the Duplex because the gold ore was found on two levels.
Searchlight declined after 1917 but hung on as a stop on the Arrowhead Highway. In 1927, U.S. Highway 91 bypassed the town and its population dropped to 50.
The town had a resurgence in the 1930s and 1940s with the construction of nearby Hoover Dam and was home to the El Rey Bordello in the 1940s and early 1950s until it burned. The last gold mine ceased operating around 1953. Senator Reid's autobiography states that during his youth the town had 13 houses of prostitution but no churches.
