I'm hoping to make some 4-pin RGB LEDs (R, G, B, GND) easily hot pluggable, so I'm wondering if 4-pin S-video connectors could be used.

Now, 2 of the pins on a S-video connector are GND, so would it be a good idea to abuse it and connect it to one of the colours? I'm just trying to cause minimal damage if it is plugged to another device with a S video female, and vice versa.

Here's the LED

  • \$\begingroup\$ Why would you plug a LED in an S-video? More to the topic, you can't damage an S-video input or output by connecting a LED to in - video signal is too weak to go through the led. \$\endgroup\$ – Dmitry Grigoryev Jun 10 '15 at 17:53

S-Video isn't very common anymore, at least in the 'states. But still, it could happen. Is this for cable-mount, panel-mount, circuit-board mount? How about something like this?

  • Get two of them for each LED.
  • Trim the LED leads flat.
  • Insert and very gently solder the LED into socket #1. Keep it cool, plastic will melt.
  • Solder socket #2 to your circuit board.
  • Connect them together.

Low-profile, easy, fast. It's up to you to make sure it's connected the right way. There are "keyed" variants of these also which make them only connect one-way.
