Alarm light on Stack instrument cluster

Just had a good ride round in the car but when I came back I noticed the alarm light on the dashboard was on. It stays on when you switch the ignition off. I set the alarm and opened the door and the alarm went off so it seems to be working OK.

Any ideas at the moment I have disconnected the battery so the light does not drain it.

I looked in the manual but I cannot see any mention of the dashboard light.

The car is a 2001 Exige with the original alarm.

Thanks for any help

Light should be disconnected… it’s not used on the Exige… I suspect something’s shorted somewhere?
