The 6v,0.6w alarm flashing lamp circuit
The 6v,0.6w alarm flashing lamp circuit(see as figure 26.4) The alarm lamps in traffic have different powers, whose working voltage can be provided by the 6V battery, such a lower voltage can be switched into the high voltage that the flash lamps need. The figured charge voltage can be regulated by the potentiometer R6, and the transistor peak value current can be regulated by potentiometer R3.
