This item is backed by a Limited Lifetime Warranty. In the event this item should fail due to manufacturing defects during intended use, we will exchange the part free of charge (excludes shipping charges) for the original purchaser. Please keep your invoice for proof of this warranty.

Bulb Note:

Unless otherwise noted, our lights do not include bulbs, though occasionally lighting manufacturers do include bulbs in the lights.

Our warranty applies only to the light assembly.

    • Pop the hood and secure it.
    • Remove the two anchor pins securing the head light assembly by twisting and pulling them up.
    • Remove the head light assembly.
    • Unplug the bulbs and harness.
  3. step : Install the new headlight assembly (1:35)
    • Plug in your bulbs, replacing them with new ones if necessary.
    • Reconnect the harness by clipping it in.

2000 GMC Sierra Headlight Assembly
To date, this purchase has been fine. Fortunately, headlight assemblies are easy to take out and put in, due to the locking pins. The plastic of these assemblies worry me, as they can crack/break easily in certain areas. However, this assembly I purchased has been fine. I merely took it out of the box, popped the hood, took the pins out, and replaced assembly. You may have to adjust the light beam up or down, etc, with the screws. I am pleased and hope that it holds up over time.
