LEDS – light emit­ting diodes – need a re­sis­tor to pre­vent them from be­ing de­stroyed by ex­ces­sive cur­rent. They’re used in colour sig­nals and man­u­fac­tur­ers fit re­sis­tors to the end of the wires. How­ever, the MAS Se­quencer also has re­sis­tors fit­ted to limit the cur­rent. You may wish to in­crease the bright­ness of the sig­nal by re­mov­ing the sig­nal re­sis­tors and just us­ing the ones built into the MAS Se­quencer.
