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. If you happen to receive a lighting product (Headlight, Tail light, parking light, fog light etc.) that comes with the bulbs, the bulbs are not covered under our warranty. Our warranty applies only to the light assembly.

  1. step : Handling the Bulbs (1:24)

    • Open the hood and secure it.
    • Pull up on the two tabs anchoring the headlight assembly

  3. step : Transfer the wiring harness clip (2:15)
    • Use a small screwdriver to pry out the little metal clip
    • Install it on the new headlight assembly wiring harness
  4. step : Install the new headlight assembly (3:40)
    • Plug in the wiring harness and bulbs
    • Seat the headlight assembly and anchor with the tabs.
