Mail Alert relay

I'm getting ready to landscape my front walkway, I used alot of 12volts relaydiagrams on my truck and both my kids cars. My father has moved in withme recently, the highlite of his day is when the mail arrives, I like to set up a censer on the small door that when brocken a line of LED go on , and stay on in the house. and have a second censer on the Big keyed door that when openedturns off the line of LEDs in side the house, I just recently hucked-up my trunk releasebutton to some 12 Volt canlights in the shell of my work truck it's the best thing aboutmy truck . Thanks to all Mark
