Here are the key facts extracted from the text:
1. The text is about the LED traffic light and its advantages over the incandescent traffic light.
2. The LED traffic light is more energy efficient, brighter, longer lasting, and easier to maintain than the incandescent traffic light.
3. The LED traffic light has a problem with snow and ice buildup in cold climates, which can obscure the signal and cause accidents.
4. The problem of snow and ice buildup can be solved by adding heaters, sensors, or altered visors to the LED modules.
5. The text argues that the problem of snow and ice buildup is rare and should not outweigh the benefits of the LED traffic light.
6. The text also discusses some other aspects of traffic light technology, such as vehicle presence detection, emergency vehicle detection, and different types of pedestrian signals.
