Open the trunk and remove the carpet from underneath the trunk lid. You'll see a small cable that comes from the trunk lock cylinder. This breaks off the cylinder when it gets old. Follow the cable up to a single-wire connector. Disconnect it. See if the security light goes out.
This safety is designed to set off the alarm and disable the ignition if someone tampers with the trunk lock cylinder. I currently have it disabled on my SSEi for this very reason. It failed, leaving the security light on at all times. A few others here have had the same failure.
I hate to bring up an old thread. But I have a 99 SSEi with this same problem. I disconnected this wire but it still stays on. Here is a picture of the one I disconnected. Hard to tell, but it is about three inches behind and to the left of the latch.
Since it doesn't work disconnecting. What is the resolution?
