Is this a set or just one?
Howard W on Aug 19, 2017
BEST ANSWER: 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.
Is it for both sides?
Tony S on Jul 30, 2018
BEST ANSWER: 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!
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 on Aug 19, 2017
BEST ANSWER: 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
What is the part number for just the headlight lens?
Howard W on Aug 19, 2017
BEST ANSWER: We do not sell the headlight lens alone. The lens is adhered onto the assembly, so it is impossible to just purchase the lens.
