I would like to use the K3505 Headlight Alarm in a car with 24V on-board voltage.
I was thinking about putting voltage regulators (kind of L7812) in front of the inputs L and C.
Would this work?
Or is it possible to simply replace some of the resistors with other values?
I’m not an expert in electronics, but as far as I see the ICs operate with an input voltage of up to 20V.
So maybe none of the resistors is responsible for voltage regulation?
In turn, does that mean I wouldn’t have to go down to 12V in my first approach? With 15V or 18V it would be easier to keep the voltage regulators cool.
Thanks in advance for your help.
