There is a new number to call to report your tower light "extinguishment." You call Lockheed Martin in Oakland, CA, at 877-487-6867. Word from the FAA is that LH is working on a website for reporting outages.
ADVICE!
The LH guys don't offer you a "case number" as the Flight Service guys did. ASK for one, so as to cover your anatomy should an incident occur before you get someone to climb.
