Final answer:
Snow removal vehicles typically use amber-colored lights to improve visibility during work. High beams should not be used in fog or heavy rain because they can reflect off water droplets and create glare, reducing visibility; low beams are recommended in such conditions.
Step-by-step explanation:
Snow removal vehicles often use amber-colored lights for better visibility during their operations. These lights help in increasing the vehicles' visibility to others during snowstorms and when visibility is generally reduced. The color amber is used because it is distinguishable in snowy conditions, which tend to mute other colors.
When it comes to using headlights in fog or heavy rain, it is advisable not to use high-beam lights. High beams can cause the light to reflect off the water droplets in the air, leading to glare and even more reduced visibility for the driver. Instead, drivers should use low-beam headlights which help to illuminate the road without causing significant reflection or glare.
It is important for both safety and effectiveness in ensuring visibility to use the proper lighting in adverse weather conditions. Vehicles should operate with appropriate lighting, notably the snow removal vehicles with their amber lights, and individuals should use low beams to reduce glare and visibility issues during poor weather.
