"Leave a distress strobe with my fighter."
―Darth Vader[src]

A distress strobe was a type of locator device designed for use in times of distress. After being rescued from his crippled TIE interceptor following the destruction of the Tarkin superweapon in the Patriim system in 3.5 ABY, Darth Vader left a distress strobe with his fighter for later retrieval.
