I did some research into a number of forums last night, and found out 2 things. 1: After being disconnected for over 20 minutes from the battery, the electrical system should supposedly "reset" itself, and this might solve the issue. 2: 2001 and 2002 Caravans supposedly have chronic problems with the connection between the fusebox and the "TIPM" (IPM). Others have solved intermittent headlight problems by removing the TIPM, cleaning connections, applying some grease, and even putting a washer or two on the screws holding it on before reseating it, and this has improved that connection and fixed their electrical system gremlins. I was prepared to mess with that if necessary but hoped that it wouldn't be necessary.
So after being disconnected (the negative line on the battery) all night, I went out and did what you said, put the key in there turned to "on" and reconnected it. My headlights are no longer flasing and everything seems to work correctly! Don't know if it was the security system like you say (because I wasn't even aware I HAD one) or the electrical system "reset". But whatever the case, it is now fixed. I'm a happy camper and my kids don't have to miss their trip to the pumpkin patch today. WE ALL THANK YOU!
