Does a broken car taillight cover need to be replaced entirely?

[OBlakely]

When a car taillight cover is broken, it generally needs to be replaced entirely. The function of the car taillight is to alert vehicles behind during nighttime driving, indicating the presence of a vehicle ahead and showing the positional relationship between the two vehicles. Taillights are installed on both sides at the rear of the car. Car lights and their functions are categorized as follows: 1. Headlights: Illuminate the road and objects ahead to ensure driving safety; 2. Position lights (width indicators): Indicate the width of the vehicle to alert oncoming and following vehicles; 3. Fog lights: Help oncoming and trailing vehicles detect the vehicle more easily; 4. Brake lights: Inform following vehicles to slow down or stop; 5. Low beams: Provide clear visibility of the road surface ahead; 6. High beams: Allow viewing of distant road conditions; 7. License plate lights: Illuminate the vehicle's license plate at night.
