This single setup works well with the following voltages (you don't have to select a voltage when ordering): 9, 10v, 11v, 12v, 13v, 14v, 15v, 16v, 17v, and 18v. These are provided in packs of 5. We typically do not believe in selling in preset packs, but in the case of the pre-wired Nano LEDs it is best for us to package them this way for handling and ultimately it protects them during shipment. Our pre-wired LEDs are nothing but quality. If you want to optimize the light output for any specific voltage and you know what resistor you want then it is very easy to change the resistor because we have added it on to the end in this particular 0603 Nano pre-wired led design. Purple Halloween Lightbulb 12v 0402 Pico SMD Wide Angle Pre-Wired LED Green Ultra Bright 12v Purple Led 12v 0603 Nano SMD Wide Angle Pre-Wired UV / Purple LED - Ultra Bright - 5 Pack - (10v, 11v, 12v, 13v, 14v, 15v, 16v, 17v, 18v) (Ships from US) 12v 0807 / 0805 Micro 1.5Hz Flashing SMD Wide Angle Pre-Wired LED White... Our 12v 0603 'Nano' SMD pre-wired wide angle pre-wired leds have built in resistors so that they will work with the voltage that they are rated for. We have done it this way because the LED is obviously meant to be used in small or confined spaces and we don't want the resistor to get in the way.

The only thing you need to do is add power / ground and they will illuminate.
