So I was dinking around with one of my LEDX bars (I know, I know, I need to be working on my 18 strobe Edge but, hey look! A squirrel!) and I think I killed one of the narrowstik heads... They have 4 wires coming off the back of them: red, black, blue, yellow. Only the red and black are connected, but the blue wire has a lug crimped on the end and the yellow is cut off at the strain relief. I had one powered up and tried grounding the yellow wire and got no result. So I touched my grounded lead to the lug on the blue wire and the head went out, and has not come back to life. I tried googling for connections for these heads but found nothing. Either sets of numbers also don't get any results. Anyone know what model these heads are and what the yellow and blue connections actually do? Thanks.
