Abstract
A system 10 for controlling automatic headlamps within a vehicle which allows an operator of a vehicle to selectively program the amount of time that the exterior headlamps of the vehicle remain illuminated after the vehicle's ignition switch 18 is turned to the “OFF” position or the “exit delay” of the system 10. System 10 utilizes a controller 22 to monitor the positions of ignition switch 18 and headlamp switch 16. If the positions of switches 16 and 18 match a certain sequence within a predetermined period of time, system 10 initiates an “exit delay” programming period which is selectively terminated by a user. Controller 22 uses the programming period as the new “exit delay” for the system.
