Tail Light Bulb Led Unit 84198978 13579168 Fit for Cadillac ATS & XTS 3.6L 2013-2018

Worked well

I replaced bulb on car and it stopped working / went out after a few weeks. It’s too late for me to return

Happy so far with it. It isn't as bright as OEM at all but it works and is bright enough. On for 2 weeks will update if it goes bad. But so far 5 stars for it being 30 bucks.

I have a 2014 Cadillac XTS and my back taillight went out. I went to the auto part store, and it was a few hundred dollars to replace it. My husband refused to pay that much, so he took it apart and found out this part needed to be replaced. We went to Amazon and found this part for a fraction of the price. I ordered and received it the next day. My husband popped it in, and I was back in business. So, I am Very Happy, and if it happens again, I will repurchase.

My brake light went out on my Cadillac XTS 2016 and I called the dealership and they told me I needed the whole assembly. The Cost was $900 to replace, I looked it up and saw it was most likely a bulb. Searched it on Amazon and purchased this bulb and now I’m good money! I looked up a video on installation on Youtube and did it myself. Saved a lot of money not listening to the Cadillac dealership and doing a quick Google and Amazon search.

It did fit the broken receptacle however that receptacle is not serviceable.

This product only worked for three weeks. I went through two of them. Very poor productI tried to return but could not for 30 days had passed. Product did not last 30 days

Perfect fit for tail lights. 2013 xts Platinum. Don’t be fooled by the dealer. Reach up under the car twist.. and unplug. Install bulb before reconnecting the plug. Takes a little effort, but you save $300+ dollars... the dealer will rip you off..!
