I was Investigating on Car headlight Alarm and how it should sound a buzzer when the headlights are on?
I have attached the circuit diagram aswell you might wanna have a look on it.
Are there any other components of this circuit which can be improved?
How can I make it smaller?
Here is what someone suggested me;
this one i am lost in which rectifier to go for as there are many but I need one which can work on 12v.
I would really appreciate if you guyz could give me a helping hand please?

But for this I need circuit diagrams as I am having difficulty in connecting this circuit in multisim.Why don’t you just put the buzzer between the two lamps
put the buzzer between the two lamps and add a rectifier in series, with the Anode facing X1 (so the buzzer doesn’t sound when the Accessory switch is on and the headlights are off). The 65ma that drives the buzzer will flow through X2, but that shouldn’t be enough to make X2 glow.
