Thing are already starting to happen. Many major cities are now using traffic lights which
use the basic technology to make much brighter green and red lights since they have a much
longer life than conventional bulbs. One US Company, Traffic Technology Inc., has even
offered to give away the lights in return for a share of the energy savings the local authority
makes! Consumer products like torches are finding their way into shops and online
catalogues whilst the automobile industry is looking at the use of LED white light for interior
lighting in cars. Major manufacturers such as GE are entering the market and targeting mass
markets such as street lighting and domestic applications, a market estimated to be worth
$12bn in the USA alone.
