I have found myself not turning my headlights off on early morning drives where I start out in the dark but then it is light when I get where I am going.
Other than some difficulty reaching the connections, this is very easy to install.
The ground goes to the IGN terminal on your ignition switch and the positive wire goes to the headlight terminal on your headlight switch. No relay or anything else is needed.
The piezo buzzer from Amazon actually does intermittent beeps. https://www.amazon.com/gp/prod...00?ie=UTF8&psc=1
