 Bude lights were fitted in the House of Commons—where it is said that he replaced 280 candles with three such lamps, which lit the House for sixty years until the arrival of electricity—as well as along Pall Mall and in Trafalgar Square where recently refurbished replicas of the two styles originally used can be seen.He extended his work to lighthouse lamps, innovating in the choice of source, the use of lenses, and the introduction of identifying on-off patterns enabling seafarers to identify "which" lighthouse it was they saw flashing.The "Gurney Stove", another invention which he patented in 1856, was extensively used to heat a wide variety of buildings.
