Just Like a New Car
We replaced a clouded headlight with this one and transferred the new high beam light bulb over to it. It is extremely easy to replace (I watched the installation video), even by someone who is not auto-repair savvy. Excellent product and price, along with fast delivery.

It fit and looks exactly as it should. Also, it came with both bulbs. I can't remember if it said it did or not in the description. I use 1aauto for many items on my vehicles that need replacing. I will continue to do so after this purchase.

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.
