It's probably just three or four 5mm junctions in series.
The reason nobody has responded is probably to do with the fact that nobody has any experience with these. I'd say it's a piece. Especially at that price.151 views and no comments, if it`s a piece of XXXX , then say so!

Looks like either a 10mm LED with an overhyped rating or something similar and at 1 watt it's not to impress... Probably has a little regulator circuit in the base. I don't trust anything from KD but if you like dealing with them then for $4 give it a shot - no big loss if it's not what you expected.
As 4 dies in series, you CAN'T simply run it off 12V in your car anyways. And if you try to ballast it with a simple resistor, the regulation from 14.2v to 11.5v is simply awful. Ballast resistors would work with a 6v or 9v string not a 12v string. A proper current-regulated buck supply will allow you to run it with accurate regulation with only a little overhead- but then a buck supply works just fine driving a 3v 1W/3W/5W LED. No need for a 12v LED there. So what did this get you? Nothing, really. And being a "rare" item you're in a dead end, if you figure out anything useful for it then one day the supply will dry up and nothing is left.

OK, it's a piece of rubbish.
Seroiusly, if you are in doubt about anything at DX, or KaiDomain, don't buy it. Your gut instinct will always be right.
