Description

Circuit schematic like in Figure 1 above is Circuit Schematic Motor Bike Brake Horn using Transistors. Electronicsproject site describe that the circuit can be operated from 4.5V to 12V DC or direct from the brake point of the motor-bike, Resistor R7 should be replaced with 1-ohm. 1/2W in case of an 8-ohm speaker. T5 is a driver transistor. C3 polarity can be reversed for a sudden off of the circuit.
