Why do you need to replace the headlight assembly of GMC Sierra-2500HD?

  • Weathered lenses

Over time the headlight lenses tend to lose their coating because of exposure to the weather, UV radiation, and specific elements. This coating is responsible for preventing the discoloration of the hard plastic. When exposed, the headlights happen to lose the lens coating and prevent the hard plastic lenses from discoloring. This, in turn, allows the light to bypass them and thus reduces their ability to shine.

  • Burned out beams

Sometimes when you turn on the headlights, you will see no lights coming out, or the only light comes out when you are on the high beam. When there is a lack of light, it is clear that the bulb filaments deteriorate. The deterioration process is accelerated with vibrations and impacts.
