RAMPS 1.4 voltage question (no replies)

I recently got a RAMPS 1.4 board, and I've converted it for use with 24 volt. I've followed the multitude of videos and articles on how to do this, which all of them are practically doing the same thing. I tend to double check why they do it, and looking at the schematics I wonder if something has been overlooked by all of the articles/videos out there.

Now, my knowledge in electronics is very basic, so I could very much be wrong. But it would be nice to know why if so.

It's basically the "HEATER & FANS" part of the schematic. In there, on the "+12v" side, it has a LED for each output (LED2, LED3 & LED4), each with a resistor in series (R23, R24 & R25). If the voltage goes up to 24V, does that not mean the resistors will have to be recalculated and replaced? I suspect that this might not matter as much and the board will work regardless, but it might "leak" more leccy than necessary and not be as efficient. The lifetime of the LEDs might also be shorter? Is this true?

I've been thinking about potentially increasing the voltage even more, so wondering if without replacing the resistors the LEDs will fry at some point. I guess the easiest is to just remove the resistors and/or LEDs as they are for visual feedback only (I guess).

Many thanks
