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
A SET! ONE FOR EACH SIDE.
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.
