Switches with built in LED?

I have been seeing a bunch of button switches with built in LED so it lights up when you press it, on ebay, and also when I google search. Is there something wrong with using these, or are they just less commonly used in battery mods? I notice most people have been using the solid cap buttons or the horn style. They look cool to me, if you like to have things light up on your mods. Any reason I should stay away from using them?

Yeah, don't bother. They're HUGE! I ordered one, waited two weeks for it to arrive from China... stupid thing is almost two inches long. Ok if you're sticking it into a big box, otherwise they're pretty useless. :(

Very slick looking push buttons for sure.. I was disappointed when I got it. The button itself is kind of small as well, works best with just the tip of the finger. I imagine people with fat fingers wouldn't be able to use them at all... lol.

That is, if we're talkin about the same switches.

I think most are oriented toward the automotive aftermarket.
12volt dropping resistor inside or 120 dropping resistor.
Surgery to the switch could be performed. I have some, I look and see what the prognosis is :)

I make one comment about LEDs. The red/orange LED takes about 2 volts to conduct enough current to shine. The blue and white ones take about 3 volts. The remaining volts that need to be dropped at the ma current running through them is done with a resistor. It is different for red vs blue and different for different battery voltages. Instead of just using these to look cool (oh I like the green LED, with a purple body) The resistor LED voltage could be utilized as part of a safety monitor. Stacked battery mods could have an LED wired for each battery and resistor adjusted to just light if voltage is adequate (under load). A power on LED and master switch is sometimes a false safety indicator if one battery is dangerously low. And a forgotten power switch (left on) could drain batteries. The next vape could be the LAST. Unloaded voltage monitoring isn't enough. Underload monitoring, each cell, would be a big safety feature. Food for thought, I don't do high volts myself.
