Our 3mm clear pre-wired LEDs are available in a variety of colours. The leads are approximately 220mm long and have their ends stripped and tinned ready for direct connection to their power source. There is no need to connect an additional resistor in series as they have an appropriate resistor built into the lead ready for connection to either a 12 or 5 volt supply. The LEDs are water clear until powered when they emit the chosen colour. Supplied singly or in packs of 5 and 10.
