Flashing LED with bonus Zombie

I am not the first to post a flashing LED for a fake car alarm.  In my brief search I found one posted by artcfartc titled "Faux Car Alarm with Flashing LED."  With that said, I have wanted to do this for a bit.

I recently purchased a old Chevy Pickup and wanted to add a flashing LED.  I already had my Zombie friend in the truck, so I thought I would add him into the mix.  The thought was to use the normally closed contact of a 12 volt relay to power a flashing red LED and the normally open contacts to illuminate the Zombie with a white or green LED.  When the truck is off the red LED flashes and when the truck is running the Zombie glows bright green.  The added bonus is the Zombie glows in the dark, so he is all charged up after a drive.

BE CAREFUL WHEN DRILLING HOLES AND WORKING WITH THE 12 VOLT POSITIVE BATTERY LEAD.  ATTEMPT AT YOUR OWN RISK, THE AUTHOR IS NOT RESPONSIBLE FOR YOU BLOWING YOUR AIRBAG BY TAPPING INTO THE WRONG WIRE, OR DRILLING A HOLE IN YOUR ECU, OR SETTING YOUR CAR ON FIRE, ETC...
