A railcar security system that includes a railcar, a first sensor having a first sensor type and a first sensor location with respect to the railcar, a second sensor having a second sensor type and a second sensor location with respect to the railcar, a first lighting group linked with the first sensor, a second lighting group linked with the second sensor, and a controller. The controller is configured to receive an arming signal, receive a trigger signal indicating a sensor of the plurality of sensors has been triggered, determine a sensor type and a sensor location for the sensor based on the trigger signal, activate the first lighting group when the determined sensor type and the determined sensor location correspond with the first sensor, and activate the second lighting group when the determined sensor type and the determined sensor location correspond with the second sensor.
