A buzzer is cool. You just connect the circuit.
dirty sensor
Use the astable to switch a power transistor and connect the buzzer as the transistor load.
take two cells a buzzer and a light join the buzzer with wire and the light bulb with the buzzer and the cell
The knock sesor is located, on your Isuzu 1290, at the front of the engine. The sensor screws into the engine. Wires connect the sensor to the senor light.

If the buzzer goes on whenever the key is in and buzzes continuously, it may be the airbag system (SRS) or an electrical problem in the SRS sensor.
Simply connect all three items in series. When the pushbutton switch is momentarily depressed, current flows in the loop. Since the 'power supply' is 25% short of the buzzer's rated operating voltage, the buzzer may or may not sound.
The headlight on buzzer must be wired to the door switch as well as the lighting system. It is not necassary to wire it to the headlights as the park light will be illumintaed at the same time and wiring it to the headlight is more involve as you have to wire it to the low and high beam The door switches are linked to the interior light and provide an earth when the door is opened, Look on your fuse cover and locate the park lamp fuse. Using a connector take a lead from the fused side of the supply (remove the fuse while the lights are on and one side of the contacts will lose power)You need to connect to that one. Run this to where you are going to secure or locate the buzzer. Connect this to one side of the buzzer. Depending on what type you are using it may be critical to get the positive and negative connection correct. So place the supply from the fuse box to the positive side. You could leave the fuse out while doing the job in case you leave the lights on and create a short circuit while working with the wires. Trace the wire from the door switch and connect a second wire to this and run it to the other connection on the buzzer. Refit the fuse and test the circuit.
It responds to the door latch mechanism. If you trigger the latch the light buzzer, door lights e.t.c all respond.
a light sensor is movement is made this triggers off the sensor which turns of the light
