Original WebRelay is a device that can turn on the backboard lights when the end of period is reached or the shot clock expires. You will need one relay for each backboard.

Technical: The scoreboard triggers the relays when the end of period is reached or the shot clock expires. The Original WebRelay gets wired into the backboard lights so that the scoreboard can turn the lights on and off.

The backboard perimeter lights are the red lights that are attached to the backboard and light up when the end of period is reached or the shot clock expires. When using with the Original WebRelay, you will also need the transformers. You will need one backboard light and one transformer per backboard. These backboard perimeter lights and transformers come in sets of two (one for each end of the court), so you will only need to buy one light pack and one transformer pack per court.
