There is no such thing as a 12v led even for common folks.

Tom you know I,m not smart enough to question you but what are those LED lights I put on my boat trailer ??[something changes from 12 vts after the plug on the truck]???

LED's are semiconductor devices, not light bulbs. They are low current devices. If you hooked any LED across 12v without a current limit circuit, the LED would be destroyed.

LED's are rated in current not voltage. A LED can operate at just about any voltage (ac/dc) with proper current limits, usually a resistor.

I'm just providing some awareness of technology and terminology for the less fortunate.

Count me as one of the less fortunate--

LED strips for making you own underwater lighting. Made for 12v operation too.

There is a current limit in the socket. Leds will not run directly on 12v. Trust me.

I know how they work, got my little AS degree in Electronics back in the mid 80's :D but this is what most are talking about. :D:D
Didn't mean to get you worked up there :p

I know. I am being complicated to keep Frank confused.:p
