Red/Green light with Arduino and remote control

We're looking to reuse some parts from a traffic light that had a simple remote control to automate it's functionality. We have: - 24V Red LED board - 24V Green LED board - Two sets of electric eyes (24V) - when the beam is interrupted, one of the wires is powered for as long as the beam is interrupted. - Two remote controls (optional) The traffic light will be used on a track and needs to have the following functionality, : When Eye 1 (start) is triggered, send a wireless signal to the traffic light to turn red. When Eye 2 (end) is triggered, send a wireless signal to the traffic light to turn green. Another way to operate can be using a two-button remote control that overrides the Eyes. One button will serve as an on/off switch for the red light, the other button as an on/off switch for the green light. Both lights cannot be on at the same time. If both lights are off from the remote, the Electric Eyes take over again. Another exception is if Eye 1 is triggered multiple times before Eye 2 is triggered. The light should stay red until Eye 2 is triggered as many times in a row as Eye 1. In other words, if two cars pass the start line, the light should stay red until both cars pass the finish.
