Yes, and? I don't see anyone arguing any different. We know they are diodes.
Would this work fine on AC?

Then lets stick with the DC.
Why?
Cos it is simpler.
How so?

Backup, please.
This is not a LED emitter. It is a LED lamp, designed for DC operation.
The original poster has a reason for running this LED lamp on AC power, and was asking for our thoughts on doing so.
The whole point of the current discussion is operating on the LED lamp on AC; it might be simpler to run it on DC, but in that case the discussion vanishes

Yes correct. Are you saying it will only work when installed the correct way and it's a trial and error affair?

Now that you mention it, I remember car interior-light LEDs having instructions saying to flip the bayonet insert if it doesn't work the first try, which suggests that polarity reversal doesn't hurt it, further suggesting that AC won't hurt it either, finally suggesting that it will work on AC.

Okay well just to be safe I ordered DC drivers cuz they're essentially the same price anyway. So we can stop talking about it - or not 
Sounds like you’ve made your decision. Still a bit of a curiosity though. If it is intended for automotive use, I would expect it to have capacitors for filtering in addition to the bridge rectifier, and would work nicely on AC.
They make bridge rectifiers in tiny DF type SMD packages..
But the simplest DC which where started on the first post. Why do you want complicate it?
I'm not complicating it. We are talking about what is possible given what is available. If you have an AC power source and a lamp rated for either, then what is the problem? Your desire for simplicity doesn't always match practicality.
This is the opening post:
"Why does it say "12v DC"?"
Because it is THAT simple.. Even I can grasp that.

I don't see how you can say it's that simple. It is obvious they do not actually need DC. Since the base is not polarized they clearly have electronics built in so do not need DC. So that is what we are talking about why do they say DC when they don't need DC? Sorry it's not that simple.
So no LEDs work on AC? Funny you say that because my house is full of LED lamps and my incoming power is AC. It's just that simple.
