How To Wire Led Lights To Car Battery. To be sure they wont light up unless you apply enough voltage but once their lit even a tiny increase in voltage will make for dramatic increases in current so your supply needs to limit the current. 12 Volt Wire.
Prong 85 to one prong of the switch other side of switch goes to a power source. Attach the negative side of the LED light to the negative side and then bring the negative battery wire back to its original position. So the basic to wiring a relay for lights would be.

LED lights are long lasting and can help you save on electrical costs. Most LED lights are arranged so that they can run off of a 12v batteryin fact 12v lights can cause a short when plugged. If the maximum current rating of these LEDs is 200mA the resistor value youd use is 02A 33v R or R 33v 02A 165 ohms. 1 Battery can power led strip light easy.
