What are you planning to do with the blue LEDs? Are you building a baybus or are you changing the power/HD led?

If you're building a bay bus, make sure that you put the right resistors with the blue LEDs (depending on how many volts) e.g. blue LED is 5V 30mA Then you would need:
(12V - 5V)/.03A = 233.33 or more ohms <--- resistor.

The typical DC output is 12V (yellow and 1 black wire) or 5V (red and black wire).
E-mail me if you have any questions. Not sure what you wanna do, your post needs more info. Email: pqtat@ucdavis.edu

Good luck

If you are using them to replace the power and HDD lights someone else used 5V from radio shack. ColdFusion718 if you are from UCDMC were almost neighbors.

I replaced the HDD and light with blue LED's from Radio Shack on my system. (KT7 nonRAID with an Enlight 7237.)

You want Radio Shack part # 276-311: 5mm, 5 volt, 30mA, 300mcd.

Changing out the LED's on the Enlight 7237 couldn't be easier. I just carefully pulled out the stock ones with needle-nose pliers. The ones from Radio Shack have much longer connection wires but I just eye-balled them against the stock ones and snipped to size. Then I slipped them in. One didn't light up so I shut off my system and reversed it. That fixed that problem and I was done.

Thanks for the part #'s Dan. I changed to a blue power and a red hdd light. That blue is kinda eerie at night.

Fatdog: You're more than welcome. By the way, I had blue and red LED's at first. However, the blue looks so sharp that I swapped out the red LED for a second blue one.

Sweet.. the blue led's are nice. I switched the power light in my old p75 compaq to the blue one.. and it looks nice.. the thing is, is that the blue is right next to the hd light (green) and since it's so much brighter than the green it looks real nice (almost cyan) when the hard drive starts to spin.. you can get really nice effects with those leds..

if you want blue LEDs for you HDD light, then you need special 2.3v ones, cuz i think a m/b will only output about 2.1 volts to the lights, so 5v were barely light up if at all

Just installed my blue LED, and it is amazing how bright and brillant the blue light coming from this LED is!

no, just use the radio shack 5v ones. I just dropped mine in and it works fine, no resistors or any messing like that. It's been that way for like 4 months now.

nickburns: I gave all the specs and RadioShack part number in my post above. Obviously a 5v LED performs just fine as a replacement for hard drive light.

I just installed my 5 Volt Blue LED's from Radio Shack, and they really kick ass. I definately think they are worth the $3 I spent on them. :)

I used the red 5v for my hdd light in my Enlight 7237, and it works just fine.

For the antex sxxxx cases 3 mm work better. YOu can just put them in teh retentin thingy. 5mm is kinda big.

Just a heads up.
