smasood Posted June 21, 2006 Share Posted June 21, 2006 I am planning to change the LED on the needles myself. The question I have, Does anyone know for a waterfall type - what voltage needle I have to buy b/c the maximum volts I have come across is 2-3 volts. Do I need to put a resistor with the LED or the powersupply for Needle is already reduced to that range. Please advise so that I can buy a compatible LED either from EBAY or Radioshack. Thanks.
