Alarm on '03 xc70 on 2003 Volvo XC70

The alarm sets but the headlights do not flash to signal that it is on. The light on the dash board does flash. Is this a software issue or something else?

May just be programming. Some vehicles you can control a function like that. may just have to consult the owners manual or dealer for specific info. that is if it is factory system. If it is aftermarket them consult the alarm manufacturer.
