This automobile burglar alarm is triggered by the door operated courtesy light switches, causing pulsation of the horn and headlights, and features exit and entry time delays with the ON/OFF switch hidden somewhere to hand inside the car. The alarm unit itself is fixed in a convenient location somewhere under the bonnet.
