King of the Road
Lucas Industries plc was a Birmingham-based British manufacturer of motor industry components. The company was specialised in the production of automotive electrical components such as magnetos, alternators, windscreen wipers, horns, lighting, wiring and starter motors.
During the 1920s and 1930s Lucas grew rapidly by taking over a number of their competitors such as the car brake manufacturer Girling. In 1999 Lucas was taken over by TRW Inc.
