Bulb Note:

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

These replacement headlights were a perfect fit, easy to replace. They also came with bulbs, that was a surprise. Most important is they a clear, and they look great.

Bright on!
Headlights with bulbs and bracket were a perfect fit and easy to install. They returned the look back to New on the front-end. Was tired of buffing off the old if costing and re-coating over and over this time on my 2002 GMC Yukon.

These are great replacements the only part that took some time was adjusting them so the beam was pointing in the right direction.
