And, from the parallel circuit rule number 3 we know that total current output gets divided by the number of parallel strings. We will want to use a low-voltage SPST switch for this system. My Cart. A very common wiring mistake that is easily overlooked is the possibility of loose or obstructed wires in your LED installation. The wire lengths can be extended, if need be, with a little splice. The take away concepts hopefully were: Not knowing what the spec sheet says, one is running a fairly large risk of failure if the current gets too high.
This is the safer better way to wire LEDs in parallel with resistors - and also ensures that you don't make the mistake that I did accidentally.
How to Install Your Own LED Light Strips
In this guide I just used your run of the mill single temperature Weller Soldering Iron. First, disconnect your car battery. As far as current pull goes, both LED colors consume about the same when powered from between 9 and 12V, up to about 55mA when powered at the nominal voltage. Does any other adjustment except beat sink required to lightup. Here are a couple options:.
