Optisoft was a pioneering company in traffic signals, and were the first to use high powered LEDs magnified by a fresnel lens for an "incandescent look", rather than discrete, directly viewed LEDs. Their first product was a retrofit for existing ICC neon pedestrian signal housings, later they designed polycarbonate vehicle signals. The city of LA planned to replace all their neon signals with the retrofits. Unfortunately there was a design flaw in that the orange driver could not handle the power surges in the LA grid, and failed, which led in some cases to them being replaced with incandescent signals, the resulting litigation bankrupted the company. They were late in the design phase of a electronically programmable visibility signal (this had a grid of LEDs you would selectively disable), the pieces of the company were picked up by Intellight who released this signal as their own product.

Optisoft signals are now extremely rare. The pedestrian signal was salvaged by a collector friend from California, and the vehicle signal turned up in an abandoned storage locker in Tennessee.
