There has to be something going on here. You guys who say they work pretty good, do not have what some of us have, no way. Mine perform just like the video, if not worse; sometimes one road sign can cause them to go dim / bright / dim / bright / dim / bright. The sign causes them to dim, which stops the sign from reflecting & causes them to go bright; light on the sign again and they dim, and so on & so forth. This can go on every couple seconds, several times before you finally get past one sign. Then, it's on to the next sign. Repeat. They drive you nuts.
I have had auto dimming lights on 2 other FCA vehicles; my 2011 Chrysler 300C and my 2015 Jeep Grand Cherokee. Although there were a few false dims here & there, for the most part they worked great, I loved that feature and was looking forward to having it on the Ram. Having it turned on, with an occasional accidental dim, far outweighed not having it, just as many of you describe your Ram. Not my Ram though, no way. None of you would use it if you had to drive 5 minutes with it the way mine works.
I'm fine dimming them manually, life is too short to get wound up over something like this. Maybe it's the build date of the Ram (mine is an earlier build) or it's just the crazy bright reflective road signs we have here in Minnesota these days. But it's something, those who say theirs works great are not experiencing what some of us are. Again, my last 2 FCA vehicles worked very good & it was worth the occasional false dim to have the feature on. The Ram, however, absolutely not.
