What is a major benefit of using LED headlights in school buses?

Answer: B — Increased visibility and longer lifespan

Using LED headlights in school buses offers the significant advantages of increased visibility and a longer lifespan. The brightness of LED headlights greatly enhances the ability of the driver to see at night and in poor weather conditions, boosting overall safety. This improved visibility is crucial for school buses, which often make frequent stops and operate in varied lighting conditions due to early morning or late afternoon schedules. Additionally, LEDs have a much longer operational life compared to traditional halogen or incandescent bulbs, often lasting up to 25,000 hours or more. This extended lifespan means less frequent replacements, which not only improves safety but also convenience for bus operators. The combination of superior visibility and durability makes LED headlights a preferred choice for school buses, ensuring both safety for passengers and efficiency for operators.
