Can I have two HDD activity lights on the same circuit?

[Therealriley]

Hi all sorry not been on a while illness got the better of me.
I’ve searched all over for this info. Most want to remove the lights and I want to add another

My plan is to have two hard drive activity lights on the same circuit powered by the motherboard (msi z97s krait edition) which then feed into some acrylic tubes which will then light up as the light passes through it.

Can I run two orange 5mm single bulb led’s and run in either series or parallel (open to suggestion) and power them both from the usual motherboard connection to flash when active.

Do I need a resistor or will the bulbs have them built in these days.
Any suggestions will help me please.
Many thanks

LEDs won't normally have a built in resistor (they are also polarity sensitive) - IIRC the HDD activity connector on most motherboards is 5v with a 330Ohm current limiting resistor built in and generally OK for about 20ma draw but I'm not 100% on that.

For advanced use beyond just the normal chassis LED it would be better to connect the output of the front panel connector to a transistor or optorelay and use that to drive the output of whatever illumination which sourced its power from another output.

If you want to power 2 LEDs I'd start with a 10K resistor on each and wire them in parallel then adjust the resistors up or down from there until you get the level of brightness you want.

Thank you pal that is all the info I needed there, it’s been a nightmare finding similar info online.

The purpose was to have two acrylic rods light up orange and work as the HDD light would. It may be simpler to just do the one or not as an HDD light.
Can’t for the life of me find someone who supplies a pre wired orange hard drive light now. But il be able to put one together.
Many thanks
