Discolight
A truck or vehicle rigged with massive speakers designed to blast music at the highest volume possible, often to the point where it just sounds like noise. They are sometimes nicknamed peynadoras (referring to their heavy use during the political campaign of Jacinto Peynado, a prominent Dominican politician).
The Discolight first started being used in Brazil in the 40s, where they call them Trio Elétrico.
