Your alarm should have a domelight output wire. Use a relay to power the domelight wire.
This turns on domelight when you press unlock for 30secs

You can have your unlock wire turn on a relay to turn on your domelight, but once you open a door, it turns off the relay.

Downside, if you press unlock and you dont walk to your car the domelight will stay on.

But then you can configure it so that your lock output makes sure the relay turns off.

I have never even done this, so i am not 100% sure it will even work, but its a thought to consider.
