I used a some aluminum from an old motorcycle license plate holder. It's basically a square. Cut it with aircraft sheers, then file the sharp edges down with a mill file.
I used the bottom plate as a drill template. Mark the first hole with a punch, then drill it and attach it to the plate with a screw and bolt. Then line it up with the bottom plate and use the plate as a drill guide and drill out the second hole. This way the plate will line up perfectly.
Choose your color, wire them up and go. I'm using a 12V out from my step-down. They're super bright on 4S when coming right off the LiPo. They're rated for only 12V, so not sure how long they'd last on 14.8s. They're cheap enough to experiment with. Connect everything up with some JST plugs. I get these from getfpv, readymade or wherever(10 pairs to a bag). Very handy.
Hope this helps any other fellow racers!
