ABSTRACT:
A headlamp control system and anti-theft alarm system share a relay which powers the headlamp circuit of a vehicle in one position and enables use of the horn in an alarm circuit in the other position. Delay times operate at ignition switch turn-off to control headlamps, if illuminated, and to permit arming of the alarm and exiting the vehicle before the alarm becomes fully active.
