You could do this the only problem I see with it is that when your typical car alarm goes off is pulses the parking lights. You would probably need a constant 12v output to keep your strobes going off contiuously. Depending on your alarm you may have a wire that is grounded when armed but switches to 12v when set off. Im sure a competent installer could figure out a way to do it if he saw your alarm.
