As you can see, it is a well known fact that reducing snow and ice build-up on LED modules is a safety issue for both motorists and pedestrians. Incandescent signals generate enough heat to minimize the build-up of snow on the lens whereas LEDs do not. Fortran’s Patent Pending "SNOW SENTRY™" is the first device specifically designed to address the potentially dangerous effect of snow build-up on LED Lenses.
