Slides right on with no issue; I just plug it directly into my PSU.
Your choice of 2 knobs.

**My instructable is still in the works, so bare with me on the how-to.**
But since this is just the case, custom electronics could be built for it!

*The vrail slice, I've included just for sizing reasons. Its not used in the build here.*

For my project, this is what I used to create this-
6 - White Flattop LEDs (Straw Hat works too, but different forward voltage)
2 - 42 ohm resistors (THIS MAY BE DIFFERENT FOR YOUR LEDS!!! Use your multimeter to check!)
1 - 10k Potentiometer (Longer neck; I believe they are called Type B)
1 - 12v circular switch (Search for 12v Car Boat Dash Switch)
2 - Terminal Connectors
2 - 2 pin Molex connectors (Opti
