The 12v 5mm blue led puts out a nice color that is sure the illuminate your product or project. Our 5mm pre-wired leds have built in resistors so that they will work with the voltage that they are rated for. There is no need for you to add any additional resistors. The only thing you need to do is add power ground and they will illuminate. It doesn't get much easier than that.The 5mm pre-wired leds come with a built in resistor, all connections are heat shrinked in order to protect them and there is sufficient wire lead on all of them.This single setup works well with the following voltages (you don't have to select a voltage when ordering): 10v, 11v, 12v, 13v, 14v and 15v. We recommend that you don't continuously run them at 15 volts, but they will take spikes as high as that without any issues at all. If you are looking for a lower voltage setup then take a look at our 9v or 6v setups that will cover the remainder of voltage ranges below 10v.
