Lifetime Warranty

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:

These lights do not include bulbs. Occasionally lighting manufacturers do leave test 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 (0:58)
    • Note: DO NOT TOUCH the bulbs- the oil from your fingers will burn into the light and foul your bulb.
    • Clean with rubbing alcohol and a soft cloth if the bulbs do get touched.
  2. step : Remove the old headlight assembly (1:00)
    • Pull the tabs anchoring the headlight assembly
    • Put a cloth down on the bumper to protect your paint.
    • Pull out your headlight assembly.
    • Unplug the harness and bulbs.
  3. step : Install the new headlight assembly (3:05)
    • Plug in the bulbs and the harness
    • Using a rag to protect your paint, put the headlight assembly into its mounting.
    • Anchor the headlight assembly with the two tabs.

Do they have adjustments to them? Some replacements do not adjust.

BEST ANSWER: If you are referring to the bulb it is not the movable socket type that can be adjusted. I do however highly recommend this product. They look and work great!
