I want to dim by at least 50% the LED hard drive activity lights on two cases as well as on some 5 1/2" swap bay drive cradles installed in these cases. I'll probably want to dim the power LED lights as well for these units. Does anyone know of a gadget made to go in-line on the wiring to facilitate this, or, can anyone recommend a certain resistor that I could solder in the + (positive) lines to make this work? I assume it's the positive line that should be spliced into with a resistor, but if it's the negative one, please confirm. I don't want to burn the house down, so I would want a resistor that could take the load with no problem. They must have thousands of resistors for this and that, so I'm hoping someone with much more knowledge of electronics than me could specify what I could look for at a Radio Shack or hardware store. I guess I'm hoping someone out there has done this and could specify a resistor that will do the job--or another way to diminish the annoyingly bright lighting on cases and such. Thanks for your time.
