and Receiver Circuit is an electronic traffic preemption device that city buses and emergency vehicles use to control the traffic control equipment.

Standby charger NB : Ketiga charger diatas bisa digunakan untuk charging aki 6 V, anda hanya perlu mengganti dioda Zener dengan Zener 7.5V, dan menggunakan Trafo/Source 9V DC. Untuk Charger #2 maka R1 juga di ganti dengan resistor 330 Ohm - 470 Ohm.
