First off apologies if this question or similar has already been asked but Ive searched and couldnt find anything?![]()
I'd like to replace some LED's inside an internal card reader with some nice blue ones to match the rest of my set-up. Problem is I admit to knowing nothing about LED's and my electrical knowledge is very limited...However, I'm pretty nifty with a solder iron!

With this in mind does anyone know of any good guides explaining the principals involved in correctly replacing/rewiring LED's, such as correct voltages, using resistors etc??
I'd like to think it would be as easy as cutting off the old LED and soldering on a replacement but I know this isnt the case. I know LED's can require different currents etc but don't know how to work this out? How would I find out what voltage LED's my card reader uses?
Again Im sorry if this sounds really simple stuff but hey we've all got to start somewhere right...!?![]()
Jim.
