So I have a 3d mag I'm wanting to upgrade to led and li ion batteries possibly what is the best way of do this I read a bunch of threads and am confused I can do all the soldering and assembly my self just ending a little help. I so jayrob's lights and the german with three leds. Is there a how to and parts list for these mods or am I stuck just doing a drop in or buying these guys prebuilt setups. Thanks
