Excellent Replacements
Highly recommend this set of replacement Headlight assemblies for The Chevy TrailBlazer. Made my Truck look better and allows me to see with full visibility, as my original set was yellowed and severely clouded.

Chevy Headlight Purchase
Purchase of headlights was quick and easy. Received the parts in about 4 days. The lights were packaged very well to prevent damage during shipment. Installation was simple and was direct match to the OEM. Online video instructions are very helpful also. I will be purchasing more parts 1A Auto!!

Thanks, Mike

Fit is perfect
Fit is perfect only complaint I have is the light pattern they throw out not as good as the originals. They seem to throw out a striped kind of pattern. But I can see going down the road at night again so thats a major plus. 1A AUTO <<< TOP Notch in service and delivery!

Only thing I didn't car for is when I was replacing my bulbs with the cheap ones that came with the headlamps...The 3 finger areas for the bulb are all the same size, so I had to be care installing into the correct position for operation of the bulbs

1A Auto Cares About Customers
Received both headlights promptly. However, 1 was damaged and I thought I was going to have to ship it back. On the contrary, the customer service representative that I spoke with said to keep it and made the arrangements for another one to be shipped out ASAP no questions asked. I found this odd since most businesses would likely want the damaged goods shipped back just to make sure the damage wasn't done by the customer before issuing a refund. FYI... the headlights were a perfect fit and the price was great... cheaper than anything I could find!!

Lastly, I just purchased another product from 1A Auto and even though I may have payed a little more for this particular item, I wanted the peace of mind that goes along with online shopping knowing that 1A Auto is a first class outfit all the way and they care about customers.

1ALHP00411-Chevy Headlight Pair
I am very well pleased with this product. The workmanship is much better than the other imitations that I had purchased. These headlights arrived very well packaged. Installation was a breeze. Adjustment was also very easy. Overall these replacements were the closest to the originals in my opinion.
