The mid 1970s saw a number of innovative appliance designs come into play as the London Fire Brigade adapted to an ever changing and more Health and Safety conscious working environment. This transit-based fire engine supplemented incident ground lighting and provided a range of tools (breaking in equipment) to force firefighters' entry into secure premises. The equipment was later introduced on other fire engines as a norm and the forced entry and lighting unit was discontinued. Here it is shown at its base station, Clapham fire station, SW4.
