Nice Headlamps
August 12, 2017
Quick shipping, nice video for installation (on line), perfect fit, and price was right. A+
Looked good in the box but will never know about on the car.
November 27, 2018
I keep getting requests to review my purchase. My on line experience was very good. However, if the customer (me) doesn't read the description correctly, they will not get what they wanted. They will get what they ORDERED but not what they wanted. The delivery was very quick and the headlights were packed with care; they just didn't fit my vehicle. Let me say that the return process was a piece of cake, other than the $22 shipping cost from the USPS. It would have been nice if the warehouse could take returns. My gas to get there and back would have been around 5 dollars. So, in closing, let me remind ALL the customers out there "READ the DESCRIPTION carefully", so you know you're ordering the right parts for your car and that will save yourself a bunch of money shipping them back. Oh and the correct headlights weren't even available. They are on back order. C'est la vie!
Never disappointed by A1 parts
January 4, 2019
Once again I received my item before expected and also the quality of the part unmatched. I would be willing to pay a little more with A1, however never had to because their prices are the best. Not to forget the video assistance A1 provides is precise and priceless. Thanks! I know I'll be back!
Mazda 3 headlights

2004 Mazda 3 head light assembly
September 5, 2019
I Ordered these two light assembly for my Mazda 3 car and it direct fit and it helped me sell my vehicle quickly
Excellent quality parts
October 2, 2019
The replacement headlights were perfect and a great price. However, what sold me on buying them was 1aauto's YouTube video that was by far the best step by step directions I've ever used. I will definitely buy from them again.
Fit and work perfectly
October 31, 2019
I purchased these headlight housings because the dealer wanted twice as much for one housing. They are exactly the same, good quality and fit well. The DIY video was incredibly helpful, giving the details of every step. I recommend these lights and 1aauto!
Fits but has flaws
May 2, 2020
I just installed the headlight set today. The video provided was very helpful and detailed. I had to purchase a socket extender since I didn't have one and a stripped screw removal kit since I had rusted screws that stripped. Overall the fit is good (wouldn't say flawless) but i'm satisfied. A few notes: - There is a bracket that needs to be removed from the old headlight set and installed to the new headlight. The right headlight did not have the screw hole to reinstall the bracket, where as the left headlight did. Not a big deal - The opening to fit the main headlight bulb into is adequate but if you have a set of aftermarket LED headlights, they will not fit into the opening as the diameter is too small. The opening of the Mazda OEM headlight set did have a bigger opening. I put in a regular headlight bulb in for now but I'll most likely drill the opening bigger one day to allow me to use the LED headlights.
Horrible quality, Horrible customer service from 1A auto
August 6, 2020
Terrible quality. Should have followed my instincts and bought from the dealership. Cheap chinese junk from "Eagle Eye" lights. Lights came scratched, missing nessacary bolt holes that i had to drill out. Also marker light housing is made like trash and the bulb assembly just keeps spinning in the housing and wont tighten. Lights constantly fog up with condensation. Lens are not manufactured properly and stick out from the fender and do not line up with the body lines. I wasted 200$ and 1A auto themselves are useless with there customer service.
