RSI LED's have around since 2006. They are not very popular on newer installations. Usually shortlines and light rail agencies use this LED. These kinds of LEDs can usually be found on newer US&S equipment. Why this LED is used, and not US&S is a mystery.

This LED is a typical design. They have a light orange background on them, which in my opinion is not the greatest idea. Also the visors on the lights are too short in my opinion. Only a 12" LED exists. No 8" LEDs are available.

This LED light operate between 8-16 volts A.C and D.C. It can operate from temperatures ranging from -40°C to +74°C (-40°F to +165°F). It claims to have a life of 100,000 hours if ran at 10 volts.

This LED has 140 LEDs total, and can be mounted with 20" or 24" backgrounds.
