What should be observed in the vehicle's lights during the pre-trip inspection?

During a pre-trip inspection, it's essential to ensure that the vehicle's lights are clean and free of cracks to guarantee optimal visibility and safety while driving. Dirty or cracked lights can significantly reduce their effectiveness, making it difficult for other drivers to see your vehicle and for you to see the road ahead, especially in adverse weather or at night.

Clean lenses allow for the proper projection of light, enhancing the ability of the lights to illuminate the roadway and signal intentions to other drivers. Cracks can let moisture in, potentially leading to further damage or malfunction of the lights. Ensuring lights are intact and in good working condition is a key component of a thorough pre-trip inspection, as it promotes safety on the road.
