Yes, providing that the combined current draw of the light and the horn are within the ratings of whatever switches on the light
now.  If you use something like

.html which draws 25ma at 12v it should be OK.  This model has two connections, one continuous sound, one pulsed, so you can
differentiate between two devices if your alarms switch to ground or just choose the sound of your choice for one.
