Here in the Kalifornia Central Valley we normally have a lot of morning fog, so it's real easy to leave your lights on and return to a dead battery.

I tried several of the normal buzzer's that I simply couldn't hear. I finally ordered a good little siren that sounds like a European Police Car/Ambulance, makes the wife jump but not me, I'm deaf.

A guy I know is a real wizard at Automotive wiring, he used a Volvo Relay, not sure of it's original intent, but now when I turn the ignition off, and the lights are on it let's me know. Works for me!
