What size resistor should i use if i fit an LED to my mod?

Thanks Piper
 
Piper that depends on what voltage and what LED you have in there - generally i use a 470 ohm for 4.2v straight through - it's a little overkill but the LED's are bright enough and not had on burn out yet :D
 
What is the rating of the led and what power are you putting through it? Check this out - http://led.linear1.org/1led.wiz
Some LEDs come ready to fire at 5v all ok so a 3.7v mod will usually be fine and just light a little dimmer.
