Good suggestions Engineering guy but the only problem is you could be held liable it it accidentally goes off when say you forget to mention it to your buddy whom you loan your car to, or the valet you allow to park it at the long term Airport Parking company or your new g-friend.

Seriously, I've had numerous cars since 1985 and they've never been broken into so long as there's a blinking light up front so it looks like there's an alarm. This includes my old Supra which was broken into 2x in front of my parents house to steal the factory stereo (had a 9 band EQ). After the light, no further break-ins including when parked at a civilian shipyard in Newport News VA (not exactly the safest place to park a car). Eventually I upgraded to a full alarm.

Oh, just make sure the light turns off when driving. This way if you have any unscrupulous "friends" they can't tell it's a fake either.
