Don't wait too long.. When I contacted NA signal and got to speak with top notch customer service.. lol It was made very clear that these are no longer in production.. This was over a year ago.
FYI
I looked on their site and they still offer them, but they are $75... more than I paid for the light. I am going to search for a discount site somewhere first.
EL1998P71 pointed me to a company called StateWire.. They have the NAS domes for $45.50 ! Will be ordering one on Monday. But for anyone reading this.. I still want a Federal if one comes avail.
