Abstract
A vehicle spot or floodlight system includes a vehicle rear-mounted light source such as a backup light array configured to emit light at a first intensity and at another intensity that is different from the first intensity. Emission of light at the another intensity is caused by an actuator operatively associated with the rear-mounted light source. A controller selectively allows the actuator to cause the emission at the another intensity. The controller allows the actuator to cause the emission of light at the another intensity only on receiving a signal indicating that the vehicle transmission is in a park or on receiving a signal indicating that the vehicle ignition is set on run, accessory, or off. The controller resets the actuator to off after a predefined time period when the ignition system is set on accessory or off, or when the transmission is placed in drive.
