You converted about 20 Whelen LINZ6's and several Vertex's for me a while back. One of the heads that you were able to exchange under warranty has a moisture problem, so I opened it up and dried it out. Now only half of the leds work. This was a blue LINZ6 that you converted to amber. I am done dealing with this problematic head, so I trashed it. I am using one of the "smart" heads you converted for me as a temp. fill in, but it only works correctly in flash mode. When I switch to "arrowstick" mode, left, right, or center out, the head doesn't light up. My question is: If I buy a Whelen amber LINZ6 from here or ebay, will the color match?
