Those didn't appear as dark as Danielle's. Maybe it's the lighting for the photo in the ad. I saw those and I also saw the description, but I wasn't convinced they were the darker ones.
I've seen someone post that these have been on their car for +3 years with no leaks. Is that the longest time frame anyone can give witness to? My OEM ones went 13 years before leaking, although, I think they failed prematurely due to a poor design of some sort.
