I am using an Iwill KK266 motherboard. In essence I have a black case and want to replace the default red & green leds with blue ones...will I need a resistor along with the blue led? Thanks gwinters 08-13-2001, 08:13 PM Usually 5VDC. Check your motherboard manual, but that is pretty standard. Bsdboy 08-13-2001, 09:32 PM Blue LED's are usually higher voltage than a standard red,yellow or green so you shouldn't need a resistor. Bsdboy MrLuigi 08-14-2001, 03:46 AM thanks guys Graham 08-14-2001, 04:57 AM As Bsdboy says, blue LED's require a higher voltage than all other colours other than white and UV, in fact it is about twice the voltage (c. 3.6V), for that reason the blue LED may appear a little dim. No you wont need an extra resistor. G SysOpt.com
