All credits go to Qnnrad for making the original mod. I simply changed the color values to match the Apaches HMD and screens.

Thanks Qnnrad for his update to 2.7.11.22041 including the additional SCAS windows. I have now included this and updated the green colors to be more night-time friendly.

As requested, I have also included Qnnrads coding to move the indicator to the bottom left corner!

Of course you can edit the colors to your liking, Qnnrad has the whole explanation in his mod:
Transparent ControlsIndicator for AH-64D Apache (position: bottom)

How to install:
Place the lua file in C:\Program Files\Eagle Dynamics\DCS World OpenBeta\Mods\aircraft\AH-64D\Cockpit\Scripts\ControlsIndicator

Or use OvGME / JSGME
