Summary: The Backlit Panel Register Lights are LED position indicators from Lavi Industries made for bright spaces where a small light would wash out. An LED-backlit panel glows through a diffusion sleeve that carries vinyl numbers or graphics, turning the whole 5 by 7.25-inch face into the signal. Graphics change by replacing the diffuser. Mounts are pole or ceiling with 12, 24, 36, or 48-inch poles, a wall mount with a 9.5-inch bracket and a rotating panel, or a portable 8-inch cast-iron base. Each light has an on/off toggle switch, and on Enterprise systems a station remote switches lights on and off. The lights are UL listed and plug into the Flashing Light Controller to flash as each position is called. They are built in the USA and used at grocery checkouts, big-box service desks, and sunlit lobby counters.
