Hi folks. Very new to this. Actually I'm just starting to plan a build which I'm hoping to fully custom build and machine.

I did have some questions about the LED modules found on the store. I'm seeing a module for the MHS V1 and a different one for the V2. What's the difference in the 2 modules exactly?

Also, would someone be able to tell me the outside diameter of the body of the LED modules at as the diameter of the lip at the bottom?

Finally, I don't have any experience in wiring LEDs and I've been trying to read up on them and I'm hoping someone can help me here again. I'm not planning on a soundboard for the moment, simply a red LED (not sure which on is the best) along with an illuminated switch and battery pack. What would I need for power, resistor and any advice and how to wire it all would be very much appreciated.
