How many years do aftermarket lamp covers generally last?

[Hank]

Aftermarket lamp covers generally last 3-5 years. Material of lamp covers: A type of plastic called polycarbonate (also known as PC resin, the same material used for eyeglass lenses) was developed in the United States in the 1960s. Genuine vehicle headlight and taillight glass covers are injection-molded using polycarbonate (also known as PC resin, the material used for eyeglass lenses). Selection of color pigments: Some high-end car lamp cover molds require particularly high precision in injection pressure and time. Additionally, the color pigments used for lamp cover injection molding should be high-quality transparent pigments for better light transmission. Polycarbonate has high hardness, strength, and toughness, along with excellent UV resistance and light transmission. Therefore, genuine lamp covers maintain good transparency and color over time.
