GaittievO Posted May 13, 2014 Share Posted May 13, 2014 Hello, I want to replace my PWR & HDD LED for red LED's. I can see there is a resistor connected to te LED's, wat kind of resistor do I need for it? Spec of the red LED's: 2,10 V 20 mA 0,042 W 20 mcd I think I found out how to calculate it, but I need to know how many V the motherboard gives. Just measured with a multimeter it gives 5V. 5 - 2,1 = 2,9 2,9 / 0,02 = 145 Link to comment Share on other sites More sharing options...
LangZone Posted May 16, 2014 Share Posted May 16, 2014 Good luck with this, I'll be keeping an eye on this thread as I have a red / black build in a 750D. The led's ar pretty dim so they don't really bother me but I always debated finding maybe a red marker or a red-ish clear tape to give them a tint. This way you could just wash it off if need be.

RocketPuppy Posted May 16, 2014 Share Posted May 16, 2014 5V is correct. Hello, I want to replace my PWR & HDD LED for red LED's.

rene mauricio Posted May 17, 2014 Share Posted May 17, 2014 If the 750D's lights are white you could simply use a small layer of nail polish to color the LED red. Link to comment Share on other sites More sharing options...
wytnyt Posted May 17, 2014 Share Posted May 17, 2014 i always use a magic marker,keep applying till you get the coverage desired... Link to comment Share on other sites More sharing options...
