LEDs and  Safety

LEDs are high intensity light sources, just as you would not stare into the sun , do not stare directly into LEDs.

LEDs are low voltage devices, the LED Microspotlite runs on nominally 12V as low as about 6V and as high as 15V, they do not take much current , about 20/1000 A at 12V ,twenty thousandTHS of one amp.

So if you wire some of these lights into a car system the voltage will be fine but you NEED to put a smaller than normal fuse inline with the feed for these lights.
LED lights, do not themselves, need high current wiring.

This advice, though given in good faith, is not comprehensive and people should satisfy themselves from this and other sources,that they have the skills and understanding to install LED products like these, in their application
