Worked just fine & camp with bulbs installed
August 3, 2017
A pain to get to headlamps on CTS but the replacements worked fine. They came with bulbs which is great, I wasn't expecting that.
Car looks new again
August 8, 2017
Installing the headlamps was not as difficult as I had anticipated. They work and look great. Everyone thinks my car is new. I continue to get compliments on a car that's 10 years old.
Cadillac CTS Headlight Pair
August 15, 2017
Headlights look and perform great. A slight imperfection was observed on the lens of the right unit (1/4" x 1/4" scuff). I did upgrade the low beam bulbs to a pair of Phillips. Headlights now function as well as new. Also, thanks for all your great videos!
Great Parts

Replacement Headlights
February 17, 2018
These were a perfect fit! They were also the cheapest ones I found and an exact match to the original headlights. It says they come without bulbs but they do not, which was a plus. Took less than an hour to install after watching a you tube video. Thanks again.
March 23, 2018
I would recommend had them installed and so far it took care of the problem of headlights burning out they were a perfect fit very pleased
Good product.
June 24, 2019
They fit great and look amazing but only thing is the halogen lights are pointed a bit lower than the original ones.
July 15, 2019
Perfect fit. Look like OEM. Very clear and bright headlights.
These lights are awesome
October 6, 2019
I purchased a 2008 Cadillac CTS and the lights were very dim. One light was totally out and it had water inside. I purchased a pair of halogen headlights from you and they just plugged in and they are awesome. Very bright and even on one foggy morning they illuminated the whole road. I will definitely recommend you to all my friends
Outstanding Quality!!
November 27, 2019
These headlights made the car look AMAZING!!! Now I wont have to buy my wife a new car. LOL. Seriously, I was very pleased with the quality and warranty on these headlights. The initial height adjustment was exactly as the original lights. Using marks on a wall, I didn't have to make any adjustments. Thank you so much. I will definitely look at you guys for my next headlight purchase.
Fast and easy to use great co to do business with

New Headlights - Great Products
March 20, 2020
I did a lot of research before I bought new halogen headlights for my 09 CTS. 1A Auto had the best price and great photos of their products. For me, it was an easy decision as long as they delivered what the advertised. Once I placed the order, I received confirmation e-mails, shipping updates, etc. They did exactly what they said they would do. The parts arrived professionally packed and I was extremely happy with the brand new product. It fit great and the new product helped me see again at night. I will buy here again with no hesitation.

These headlights work great and look great than the factory ones
great company
May 30, 2020
Got both headlamps after one lens was destroyed by a deer. Unfortunately one low beam did not work after installation. I contacted 1A Auto and they had me a new one in 3 days. Product fit perfect. This company will be my automotive go to from now on. A+ rating in my book!!
Headlamps Replaced
November 14, 2020
I would definitely recommend A1 Auto to everybody. I needed to have my headlights replaced. They were so oxidized I could not see at night. The three estimates I got were so expensive. I found A1 Auto had what I needed, reasonable priced, and a how to video came with it! It was so easy! I am a Senior woman and I did it my self. Thank you A1 Auto!!
Great Product!
April 6, 2021
Only regret I have is I should have replaced these along time ago. Exact fit just like the originals and look fantastic! Ordering the taillights next!
Great it

These worked perfectly
Small wiring problem in headlight housing.
June 14, 2021
The driver side high light had a white wire stuck in front of the lens inside the headlight case. Had to open one of the bulb covers to move the wire from the front of high light lens to the inside of light housing. That fixed the problem and everything is good now.

Excellent all the way around
September 8, 2021
Packaging was excellent, shipping quick and on time, product fit perfectly. I am a big fan of 1AAuto due to their consistency in product quality, price and ease to do business with.

Worst headlights ever
January 19, 2022
These are the worst headlights I have ever had! I have been driving over 50yrs and these headlights are Terrible. The low beam has a stair step cut off line at the top of the illuminated area, causing a completely black area above the beam. Nothing at all like the OEM headlights. Driving in the Ozarks with our hilly and curving roads, these headlights are Useless without the highbeams. If you drive anyplace without street lights to help you, Do Not buy these headlights!!! They are dangerous!!! They really dont even deserve one star. These are not a simple installation but I have got to get these off of my car before we have an accident!
Customer Q&A
can I replace high intensity discharge assembly's with halogen assemblies? is electrical connection same
November 28, 2018
Jack B
Hijack there are halogen bulbs in the assemblies for both high beam and low beam
November 28, 2018
You will not be able to replace the HID assembly with the halogen assembly. They have different connections on the back and will require further modification which will void warranty. If the vehicle was originally equipped with HID headlights, you would need to replace them with HID headlights.

Can I install led lights in these headlamps?
January 13, 2019
Bradley P
Lights are bright enough, they came with the bulbs which are supposed to replaced but they're bright enough and gorgeous, no probs. I've had to pull the bumper twice to do these lights. You don't need led. Stick with stock. If u can't see with these don't drive. I've heard led can effect more than ur headlights, random aggravation.
January 13, 2019
You are not able to have LED lights within this assembly.
January 13, 2019
Emma F
Yes, but the headlight lens will allow water in them if you park outside, these are not good quality.
January 15, 2019
you can but you first have to remove the front bumper cover

Does this use the same bulb size as the OEM one do?
November 12, 2019
Bradley P
Thanks for your inquiry. Are parts are designed to be direct replacements, so they will use the same bulbs as your OE headlights. Please let us know if we can be of any further assistance.

If I have HID which bulbs are required?
December 7, 2021
Yohary C
These headlights are only compatible with models with halogen headlights. If the vehicle originally has HID these are not going to be correct.
