The 6v 3mm orange amber led puts out a nice color that is sure the illuminate your product or project. Our 3mm 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 3mm 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): 3v, 4v, 5v, and 6v. If you are looking for a higher voltage setup then take a look at our 9v or 12v pre-wired LEDs that go up to 15v.
