Basically a specialised timer that alerts you with a flashing LED when school zone-reduced speeds are in force. The unit will flash for the whole time the restrictions operate in the morning and afternoon. The only visible sign for you is a dashboard flashing LED; all other components can be mounted remotely, including the disable switch. The kit includes all specified components, double-sided PCB and case with machined and screen-printed lid.
