    Have 2 freezers and 1 fridge all uprights in garage. Have a little strobe light i found in my junk box. Want to put switch (micro,proximity...etc) on each door to signal when open. Would i connect all in parallel and go to a relay then on to strobe ? Just bare bones off/on no timers .....

    Yes, that would probably be the easiest way. Are you okay with the strobe flashing every time you open any one of the doors?

    Yes that wont be a problem. Strobe will be mounted on wall above the units, only time flash will be visible would be when i'm re-entering the house...99% of the time it's ME leaving one open....
