I used the testors panzer olivegrun 1943 on mine. It's the color that RS found for us for the buckets, and I think it looks pretty good on the gauntlets too

EDIT: Oh yeah, there are 2 leds on the right gaunt, one red, the other clear. The real switches are some type of tiny rotary switch I believe, and are most likely european in origin if memory serves. The last time I rember reading anything about those, they had not been identified. I think most people are using tiny toggle switches that you can pick up at radioshack. Hope that helps
