CT’s headlight package
Great deal, what a difference new headlights make. Not easy to install, had to pull the whole bumper cover off. Wonderful product

Cts headlampss
They fit awesome great customer service and a awesome product......
December 12, 2018
They are low, and my beams look crossed eyed. One points up and the other points down it’s weird and I’m disappointed.
April 10, 2019
Ordered in a Sunday and they were here on Tuesday, this is the second time I have ordered for my car and I have been very impressed with the overall service and price. Will use 1A auto for all future parts for any car that I own.
May 3, 2019
Great product, looks great.
July 10, 2019
I am overly thrilled with my purchase. I havent heard much about 1A Auto but I sure will recommend them to family and friends. My parts shipped quickly and they were packaged secure.
January 22, 2020
Good Purchase
Decent fitting lights for my 07 cts. Little bit off of being flush to the bumper but not to bad, can’t complain with an aftermarket set of lights for this price. This was my first purchase from 1A auto and I would recommend to others.
January 31, 2020
Super Sweet purchase and tech support experience!
The vehicle fit was accurate, the items arrived in 2 days well packaged, I went ahead and upgraded the bulbs, and when I contacted support about adjusting the headlights, they helped me within a few minutes, so, I have fallen in love again! Why cant everything be this easy? It will as long as 1A is my preferred supplier of parts for my Caddy.

Great product looks awesome
Fit in place perfect no issue

Headlights look really nice
Real nice product until the adjuster broke off the one assembly.

Headlights/Parking/Fog Lights
Lights received in three days for my Cadillac CTS. One of the headlights was inoperable. Replacement received before I could return damaged product. Guys that I spoke with was very professional and understanding. I now use 1aauto exclusively for internet purchases.

Customer Q&A
Ask a question to 1A Auto customers who purchased the product
Is this a set or just one?
Howard W August 19, 2017
It is a set
Jason B August 19, 2017
The set includes left and right headlights. I replaced the headlights on my 2004 CTS and they fit fine. I did however switched out the bulbs before installing them to a more brighter white light. The light bulbs that the lights come with are a bit yellowish for my person taste.
Francisco F August 19, 2017
This is a set. Pretty high quality as well and when I bought it the bulbs were included.
C M August 19, 2017
its a set. says light bulbs not included but mine came with bulbs.
T O August 20, 2017
and yes it is a set
T O August 20, 2017
V A August 21, 2017
Boy is my face red. I went back and looked at the product description. The first line, I mean the very first line, says that it comes as a "pair". Sheesh... Thanks everyone for your answers - sorry for wasting your time.
Howard W August 21, 2017
Its a set.
Francisco C August 22, 2017
My current set is all black except for the lens cover. These look all black. But the video looked like silver with black trim. Are there color choices?
Howard W August 19, 2017
Howard I am not aware of any color choices but if you buy new lenses make sure they are OEM or they will not fit properly
Clyde P August 19, 2017
The trim around the lens and assembly is Black. The hue of the lens(glass) is darkened but it looks pretty cool. This replacement fixture looks better than I expected. My CTS is Black with a two year old paint job. Get the pair
Wm S August 20, 2017
They do look dark in the photo but they are not black. They are exactly like the lenses that are in the vehicle.
Teena A August 20, 2017
These lights are just like the ones in the video. The completely black lights are for the CTS-V model, but we do not carry them.
Tim K August 21, 2017
What is the part number for just the headlight lens?
Howard W August 19, 2017
I was told by a few dealerships that they only sell the entire assembly and not just a lens.
C M August 19, 2017
We do not sell the headlight lens alone. The lens is adhered onto the assembly, so it is impossible to just purchase the lens.
Tim K August 21, 2017
Is it for both sides?
Tony S July 30, 2018
Yes, this kit will be a pair of headlights which will include a driver side headlight and a passenger side headlight. Please let us know if you need any further assistance, thank you!
Jessica D July 30, 2018
Yes, they are for both sides.
Francisco F July 30, 2018
Yes it is
M J July 30, 2018
Yes, When you purchase the pair, its for both sides. They will ship in separate boxes.
Stan C July 31, 2018
MIKE K October 30, 2018

We do not suggest any modifications or offer any instructions on how to modify as all of our parts are listed to be direct replacements of the original equipment and are meant to be a plug and play option. These items will not fit or function on your application. Thank you.
Jessica D November 1, 2018
Does this set include new bulbs?
Gerry S November 30, 2018
New light bulbs are not included. Occasionally, manufacturers leave test bulbs in the lights. If you receive test bulbs, replace them with your original bulbs or with new bulbs. Thanks!
Adam G November 30, 2018
Does this fit the 2006 cts v ?
Alejandro A January 9, 2019
Yes, according to the information you provided, this part will fit your vehicle.
Jessica D January 9, 2019
What tool do I need to adjust the beam of the headlight?
Steven W June 20, 2020
Philips head screw driver
Matthew S June 20, 2020
Thank you for your inquiry. There will be an adjusting screw on the back of each headlight that will allow you to adjust the beam. The best way to accomplish this is by pointing the headlights at a wall at night and turning them on, then adjusting each side accordingly to the correct level. Please let us know if you have any further questions.
Anthony C June 20, 2020
What bulb is in projector housing?
Ricardo L August 4, 2020
Thank you for your question! These do not come with new bulbs, but they will take the same type as factory. Just make sure that you do not have HID units, as these will only work on models that use standard halogen style bulbs.
