I bought one of these.

It comes with a sheet of paper with operation / maintenance and limited warranty written on it.
I used it 4 times in my car which has a 12v battery with no problems. On the 5th time It made a loud popping sound and smoke came out of it. I turned it off immediately and inspected it and no damage was visible. I called the Deltakits supplier where I purchased this from and was told not to put it into a car cigarette lighter, it needs to go into a 12v rated battery pack as a car does not have a fuse between the battery and lighter port and the light can blow due to fluctuations in the batteries charge. For an unknown reason the light still works and the supplier has agreed to fix it.
In the operation section of the manual that comes with the light it states:
Plug the light into any standard cigar style 12 volt receptacle.
I have ordered a second light and had it delivered while I send the popped one back for repairs and have bought an extension cable with a 12v fuse to prevent this happening again and if the light fails I have a replacement to continue working.
Both of the lights tinkle when I shake them like something is floating around inside both of them, anyone elses light do this or should I contact my supplier ?
Also, should my original light be covered under warranty seeing as the instructions indicate using a lighter style 12 volt receptacle is perfectly fine ?
It took a little convincing on my part for the supplier to have a look and have my light repaired. Im hoping he actually does have it looked at and does not just turn it on, see it lights up and sends it back
