Re: [Amc-list] Blue LED tamed

OK, I give up!
:] Since I now have a too bright led with a dead resistor, what do I install to get it as dim as possible and still lite???!!!
150 ohms? 15K ohms? Anyone know what the resistance is of say a 194 lamp? Maybe I can use some of those to gauge what resisitor I need?
I just need a blue glow for a high beam indicator, or I'm going to surrender and use th eleftover red one I have! It ain't broke and is fa dimmer than the blue laser!
