Has anyone out there tried these (http://www.otlighting.com/index.php) retrofit beacons? Seems like a great idea -- almost too good to be true. With the FAA about to allow us to turn off the steady-burning side markers to protect birds (http://www.radioworld.com/article/faa-preps-for-tower-lighting-changes/214077), I'm thinking that this might be a good time to transition to an LED system. Opinions?
