Light emitting diode (LED) light sources for grade crossing warning flashing lights offer significant advantages over incandescent lamps traditionally used in these applications. Improvements in conspicuity/viewing angles, power consumption, longevity, routine maintenance, etc. are rapidly changing the landscape. As with the traffic signal industry, the market for these applications is clearly moving in the direction of LEDs.

A number of obstacles have prevented wide scale implementation of LED signals; these obstacles have now been largely removed

These obstacles have now for the most part been removed, creating a path for full implementation and retrofit programs (the benefits of transitioning from 8" to 12" pale in comparison).With the W-C-H LED 12" and Gate Arm Flashing Light Units, improvements to motorist safety, railroad operating expense and product life cycle costs/ROI are attainable.

The time is right to begin eliminating the incandescent bulb from as many places as possible in rail and transit applications.
