I found an interesting video professing to show why 360 degree/3+ sided LEDs are not good. Of course, the comparator bulbs just happen to be ones the maker of the video sells. That may be expected but what is noteworthy is that when showing "how bad" the 360/multi-sided LEDs are in projector bulbs, suddenly two LEDs used in the non-projector set-up test suddenly disappear from the comparo. I find that very compelling, especially when both the LEDs that disappeared are the 360 degree dome type LEDs. (Plus, the test overall shows the other LEDs performed far better in the projectors than they did in the standard halogen set-up - something I have been led to believe should be the opposite.)
So, when a test item that is supposed to fail mysteriously disappears from a comparo without explanation, it's reasonable to assume it's because the item didn't fail as desired/expected.
Kind of reminds me of that time a long time ago when Chrysler called to find out how I was enjoying my brand new 1989 Grand Caravan and as soon as I said I was in the middle of a lemon law buy-back, our phone connection mysteriously disconnected.
FYI, I am not currently using any 360 degree/3+ sided LEDs in headlights at the moment. But I really am trying to get some honesty, not just people/businesses pushing their agendas.
Even more interesting, the brand of the typical 2-sided LEDs that the seller who make this video is pushing only has 2 H7 bulbs listed on its webpage. And both of them are multi-sided, domed LEDs.
My other car requires H7 bulbs and for the last 5 years I have sworn by these hot both High and low beam bulbs
So for my new to me 2012 GL 450 H7 lights I think I will try them and see if how they stack up.

don't know where to post this... but hopefully in reply to your post
I've read about three different long threads about replacing H7 bulbs in different Mercedes models, and I feel like I'm in a physics class for which I forgot to take the prerequisite course... all sorts of basic terminology I haven't learned and lots of arguments.
Can you please try to explain to me as if I were 12 years old... if you were replacing your H7 low beam bulbs in your C207 (mine is 2012), would it be another Hologen, or would you buy LED bulbs as you show in your post the Auto One LED? If so, do those LED bulbs fit into the place of the Halogen bulbs without changing housing, adapters, or anything else?
I replaced the low beams in 2020 based on I'm not sure what advice on here with some Sylvania H7 bulbs... I almost never drive at night so I'm surprised I'm getting the Check Low Beam warning on my dash... no way those bulbs have more than 500 nightime hours on them.
As for H7 LED bulbs on Amazon, by far the biggest seller is the Beamtech, at $39 with 37,000 reviews, and then a brand TechMax at $30 with about 4,000 reviews. All the other brands of H7 LED had fewer reviews than those two, with the Auto One having a little under 700 reviews. But... in another recent thread, it appears that some of the largest OEMs in the world are now making H7 LED that appear to be intended as a replacement for H7 Halogen... in particular, also on Amazon, the Philips UltinonSport H7 LED Bulb . If I order H7 LED, I would certainly prefer for it to be a Philips than a lesser brand.... assuming it will work in my 2012 E350 Coupe.
Thanks.

On my 2012 GL450 I have the ones pictured for my high and low beams. I am very happy with them. However I would not recommend them to others. First thing to install then the bulbs have a tab have to be flattened to fit. Not a big deal to me but you have to know that the actually do it. That in its self is too much for most people. The second reason is when you first turn on the lights they flicker one time. It's very fast almost like the heat up or something, the flicker will set the message the check the light. That also does not bother me as I just cancel the message. Others may not be happy with that. Other than that they are plug and play. Pop them in put the dust covers back on and drive away. Great for me but others might annoy me about those two things mentioned.
