What it does

Adds various helpful LED "indicators" to enhance your ships. Broadly speaking, these fall into two categories:

  • Standalone parts: radially attachable LED lights with customizable colors, which can be toggled on/off with action groups.
  • Enhancements to existing parts: add LEDs to stock parts to provide a visible, automatic indication of part status (such as whether a fuel cell is on or off).

For details, please see the IndicatorLights wiki, which includes a complete player's guide and modder's guide.

How to install

Unzip the contents of "GameData" to your GameData folder, same as with most mods. (Note, includes ModuleManager.)

Note: You may also want to take a look at IndicatorLights Community Extensions, which includes community-supplied patches to add indicator lights to various popular third-party mods.

Things to like

  • Lots of neat features; see gallery below, or the player's guide for full details. Or check out this video review by Kottabos.
  • Lightweight. The "lights" don't actually illuminate anything-- they're just emissive textures that "glow". This means they're computationally cheap and you can have lots of them.
  • Very modder-friendly. Extraordinarily flexible .cfg design allows modders to create remarkably complex behaviors without needing a single line of plug-in code. And it's very thoroughly documented, with plenty of examples, to make it very easy for you to mod your own parts using IndicatorLights. See the modder's guide for full documentation.
  • Third-party mod support is available via IndicatorLights Community Extensions.
  • Configurable colors. All colors in the mod are player-configurable. (Handy if you have color-blindness issues, or simply don't like my default color choices.) Details here.
  • Support for Making History parts. 'Nuff said.
  • More on the way! I'm not done yet; still adding new content and features.


(please see the player's guide for full details about these features)

More on the way

As described above, I'm not done yet.

Please see the IndicatorLights wiki for planned features.

Feedback welcome!

My main motivation for making this available when it's still a pre-release is to give folks the chance to try it out and let me know what they think, including "gosh, I'd sure like it if it could do {thing it doesn't do now}."

A note of thanks

Deep gratitude to NecroBones and VintageXP, both of whom provided patient, expert instruction to a clueless newbie (i.e. me) who didn't know Blender and Unity from a hole in the ground. This is my first parts pack, and I would have been totally at sea without the help of these fine gentlemen. Their assistance made this mod possible (though they bear no blame for the crudity of my models, that's entirely my own!)
