12v MR16 LEDs not working

My recessed lighting fixtures have historically used these 12v halogen bulbs, and they work just fine minus lasting only a couple months:

However my local Home Depot now only stocks LED versions.

When I plug in an LED version, the light will work for about 5 seconds and then turn off.

Any ideas here?

Previous ideas have been around 120v vs 12v, but I made sure that I am using 12v LED versions and nothing.

Are they on a dimmer? Post a link to the LEDs you are using.

You also need to check if your fixtures are 12 volts AC or DC. Many many low voltage lights using halogen bulbs were AC but a LED might require DC.
