Well gang,
I've purchase ALL my LEDs from superbrightleds.com and, we're talking at a minimum, 30 + LEDs for various fixtures all over/out/inside this coach and, never had any issues with heat or damage or, burnt out units. They've been in there now for over three years. Yeah, I may have paid a bit more than many of you ordering direct from China but, the quality of the bulbs and the "offering" of outstanding service, including instant returns should any problems arise.
And, I've been goofing around with them for quite a while and, to the best of my knowledge, an LED CANNOT USE 12VDC!!! It will burn up almost instantly. It is my belief that, they must be stepped down in voltage. And, if I recall, the max they can actually handle is around 2.5 - 3.0 volts DC. When you look on all LED light strips (just purchased three of them) you'll find a zillion resistors along the total length of the light strip.
And, in the pictures below, you'll see that I had to use resistors in building my little project of "turn signal arrows" in my mirrors on my 2008 Honda GL 1800 Goldwing. When you purchase regular, over the counter LED bulbs, ALL OF THEM will have built in resistors. You may not see them but, they're there.
In one of my early tests of a RAW led bulb, the same kind you see in the pictures, I applied 12VDC to one of the bulbs and, it was like a flash bulb on the old cameras, you know, the ones with what looks like steel wool inside them, it flashed just about as fast as those old bulbs did. Then, OUT! So, to the OP, unless you're having EXCESS 12VDC in all other applications, i.e. water pump, other incandescent light bulbs, and other 12V powered components, I'd definitely say you got some bad LED bulbs.
