General Information:

In the mid 1990s, the Roads and Traffic Authority introduced Quartz Halogen signals to New South Wales. These signals offered lower power consumption and better light output than previous signals. The RTA replaced a large number of signals across the state with these signals. Most of which are manufactured by Aldridge Traffic Group. In NSW a QH signal is recognisable by the small cross shape within the lens of the signal.

In 2005, the Roads & Traffic Authority said that about 30% of New South Wales’ traffic signals use 240-volt globes and the remainder use Quartz Halogen technology. This figure is now changing with the official introduction of LED signals in 2004 to NSW. 1
