SAFETY JUNCTION BOX

An e-stop relay system can include a relay junction and a circuit. The relay junction can include a relay to control an operation of a vehicle. The circuit can communicate with the relay junction. The circuit can receive a plurality of signals that correspond to operation of the relay, detect that at least one portion of the e-stop relay system has failed, and transmit one or more signals to a light source to cause the light source to produce light that indicates that the at least one portion of the e-stop relay system has failed.
