A Clean Car is a Happy Car! – Problem

My “A Clean Car is a Happy Car!” was blinking on and off nonstop for no reason.  I checked the eyes and there was no transmitting beam so the problem was with the Banner eye.  I was going to swap it with the under carriage eye when I figured out that the wires had just cracked out of the wire nut, which was very weird but good because the eye was not bad.  So I attached the wires and everything was okay!
