Hey,
I bought the same Cougar Motor H11/9005 on Amazon too.
Installed 9005 first as they were easiest, no issues. They run fine on DRL no flickering and the brights are BRIGHT!!!
As I was running out of daylight to installed I then went for the driver's side low beam first. I figured if I could get the difficult side finished first w/o taking out battery that the passenger side would be no problem. Boy, was I wrong!
The light just would not fit in no matter what I did. I changed o rings from stock light, I watched a video to make sure I wasn't missing something random.
I put the stock bulb back in just to prove I could do it, and then continued to struggle for 45 mins trying to put this stupid bulb in. I called my husband to come out and look at it. He struggled also, until we had a EUREKA moment!
He was holding a flashlight watching me try to install the LED bulb when he saw that there is a small piece of metal blocking the entry of the LED bulb housing.
Once he saw that, he used his grinder and barely shaved off 1/16" to 1/32" of the area I circled in the picture.
You have to line it up to see exactly which area to sand down bc the tabs are different sizes.
PERFECT FIT, and the lights are amazingly bright.
Hope this helps someone else.
