Currently these signals are not warranted, but when the development to the SW is completed they will trigger the need for these lights.
IN order to get the developer to pay for the installation of these signals we had to have them install them at the time of development, otherwise the cost would have be borne by the City.

That sounds perfectly understandable, but until the developer builds the roads, I suggest turning the traffic lights off, or running them as flashing Amber and red.

The signals are under a two year warranty. In order to make sure we get the most out of this warranty period and ensure their are no issues in the future these lights have been put into full operation. At the end of the warranty period we could consider this dependant on what development has occurred.
