Noticed the lights were flickering on and off and the security light would flash. Took it to the dealer I bought it from and they told me it was the ECM (engine control module). It was worn out and needed to be replaced. It cost a pretty penny but I haven't had any problems with the lights since.

I was told that it was the security system that was doing this but nobody knew how to fix it or unplug it.

I wish I knew what was wrong with my car. The dash lights, headlights, all the lights flicker, it drives me crazy.
