I did some work in Cedar st Lurgano earlier this week, and passed through two school zones that have Peter Olsen's "home made" flashing lights telling all and sundry that it was school zone time.
These cheap lights have been working flawlessly much to the delight of locals and through traffic alike, for over two and a half years.
This afternoon I passed by one of the RTA favoured systems in Taren Point rd and took this photo.
The overhead flashing light unit was out... AGAIN (see category "About faulty flashing lights")

Luckily there is a spare independent unit as backup, and as the RTA favoured systems have the handy fault reporting "back to base" feature it should be repaired soon .....
The one that was working does so at a pathetically slow rate.
They flash too slowly to attract attention.
Maybe the thinking is that if it flashes slowly the bulb's last longer.
