matrix model 10 troubleshooting

I have a 2003 Crown Victoria LX and have a Clifford Matrix model 10 security system.
I noticed that the flashing lights feature no longer works when arming and disarming via remote so I brought the control module down from under the dashboard and put a test light to the white wire from the CM and armed and disarmed it, the test light picked up nothing.
I then disconnected the white wire that led from the CM to the brown wire it was connected to where I assume is the headlight wire under the dash.
with white wire from CM connected to nothing I then put the test light on the white wire terminal and armed and disarmed it and the test light picked up a signal.
reconnected the white wire from CM back to the brown wire for headlights in the dashboard and tested for a signal on white wire on CM and no signal.
Interesting thing during me testing was when I armed and disarmed the CM would make clicking sounds whether the white wire was connected to the headlight brown wire or not.
what could be the problem?

It's all about the journey the destination is a pit stop.

Bad power feed: corrosion, oxidation, bad connection, or other high resistance in the circuit. A possible solution would be to put an external relay in to drive the parking lights.
