There are multible ways to add LEDs to an armor.
Some people are using plastic lenses to create as much glowing areas as possible with the fewest amount of LEDs possible.
Others go for indirect lighting. And there are also those who are letting their LEDs show directly.
In the end it is a question of how much effort you want to put into it and how good you want it to look in the end.
But for all methods, the "workflow" is the same:
- Decide where you want to put the lights and how bright you want them to be
- Pick a method that fits the light effect you are aiming at
- Search for the proper "carrier" (custom build circuite or just a hacked flashlight)
- Prepare your armor by cutting space for the lights
- Wire everything up
- - Enjoy
Do to the lagg of time I can't do a full research for you right now, for ingame and concept art for the type of armor you've build.
But basicly all you do is to google screenshots and such which show you the position of lamps on the original.
