Bulb Note:

These lights do not include bulbs. Occasionally lighting manufacturers do leave test bulbs in the lights.

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.

New headlight for old Mustang
Recently bought a 2000 Mustang GT conv as a Christmas gift to myself. Everything looked great on the car except that the headlamps were cloudy. I bought new ones from 1A and had them in quickly after watching the video. Great fit and now my Mustang looks fabulous! Thank you 1A!
