These light bulbs are ok so far, but I felt deceived when I purchased them because I didn't realize they are so cheap to buy because they are NOT original OEM parts! I thought they looked identical, but upon receiving them they are not identical. I am praying they last as long as the more expensive bulbs that originally came with my 2011 CTS Cadillac. I was lucky this time around I knew someone to replace them for me for free, but I may not be so lucky the next time. Now I know why one single bulb at my local Autozone store cost me $101.00 for one Sylvannia replacement bulb while I purchased these two lightbulbs for only $43.00!!
The bulbs matched my OEM bulbs exactly. They are bright like new and it made a huge difference on lighting the road on my 2014.
Just a heads up if you own a MB ML350 - they are tough to install - crummy access through the wheel well and a small hand hole. This would be the case with any bulb you get as a replacement. Look for the right YouTube video and you will get them out and in!
