Headlight replacement parts 2003 Chevrolet S10
I was very excited about getting new headlights for my 2003 Chevrolet S10. The pictures for the product were exact replicas of the originals. When I got the product I found the headlights to be vastly different from the pictures and nowhere near even closely resembling a replica. Very disappointed 1aauto would sell an item of this quality. Items were sent back and I would not recommend anyone buy this product. Would have rated the product lower than 1 star if I could have!

Not quite perfect
Shipping was fast. Right side light assembly was perfect. Left side had one of the lower clips broken off and the turn signal bulb fitting was cut poorly. The bulb still fit and locked ( I hope ) and I installed it this spite of the short comings. Five stars for right side, one star for left.

Headlights were perfect
I was skeptical ordering these online, but I was very pleased with the product.They fit perfectally and were very easy to install. They were shipped faster than I expected and arrived in just a couple of days. The two online video thsat 1A Auto had on youtube explained the installation so well that my 18 year old grandson did must of the install and kept correcting me on how to do it, because the video show him how it SHOULD be done. I would gladly recommend 1A Auto services.
