Small 4 pin RGB light?

[Bitter]

I'm having a hard time finding a specific product. I want a small 4 pin (12V) RGB light to connect to a motherboard header for an external CPU temperature indicator on the outside of a case. I don't want a big long strip that's cut down, I'm looking for a more finished looking product like maybe a small diffused device in a plastic housing with a nice cable on it. I don't know quite where to look for something like that, when I'm searching Amazon and eBay I must not be hitting the right keywords. Any suggestions?

I said I don't want strips or to cut down a strip, I'm just going to assume you didn't understand what I was asking since you linked Amazon Germany and English may not be your best language.

I've looked for something similar in the past and couldn't find it either.

I don't know why they don't make stuff like that when they seem to make every other kind of nonsense.

Same. I'll keep looking and post anything I find. I thought about building something but I'm going to need to do some learning first. I'd be OK with a small LED surface mounted in the case itself like the front IO and power button panel.

Something like that LED with a small buck driver to drop voltage to the correct level from 12V that the RGB header puts out, but I'm assuming that the 4 pin header controls the separate colors by giving them ground?  Assuming with electronics leads to the magic smoke coming out of them, I've learned this the hard way.

 

I guess new question is, anyone know how 4 pin RGB controls the colors? There's 12V (positive) and then R, G, B channels. Are the color channels grounded to turn on the colors and then grounded at different amounts to turn on the separate colors inside the LED?

there are argb defused strips but don't no about rgb hmm maybe nzxt sells an defused rgb strip

Since I want the light on the outside of the case I'd like to avoid a strip. I think I'm going to try carefully probing the 4 pin RGB header on the board to see what's doing what and then determine if I can execute my plan to just pop a 5mm diffused RGB LED into the front panel to have rough indication of CPU temperature. I told her as long as it's green or blue it's OK, if it's red then I need to see the PC to clean it for her and check it over.
