Well, the wire going between the wires could be grounded out somewhere. It probably is unlikely that the led is bad, if it where then the led's probably wouldn't work at all.

The DEI alarm is probably putting out only 2 volts, meaning it will only have power to run 1 LED in series. You need to run them in parallel like misterjimbo said above. or if you haven't tested them individually yet, I would reccomend that also...

if you're only wanting to add LED's to add to the "flashing light" theory inside the car, why not get 12V self-flashing LED's? Use the starter disable output to trigger a relay, and turn on 10,000 of these if you want. I've been using em for years with great success.

Ocelaris: Even according to dei, you are supposed to wire led's in series and you can have upto five. If you wire them parrallel then they will try to draw to much current and burn the led output out. Also I have 5 led's wired in my car and they are in series and have worked fine for the last 3 and a half years.

You cannot use a relay for this application. If I remember, you have a dei alarm and they only put out two volts to the led and it won't energize the coil in the relay. Not saying it can't be done just not with a relay.
