And if you choose Lithium AA batteries they are guaranteed to last a minimum of 10 years in storage.

I think these are already as approved as they are going to get, but there is the "new" laser flairs that has the rotating head, that is being approved is called the ODEO Laser Flare.
Odeo Flare :: #1 in Laser Flares
Looks kind of cool, but I am not sure I like the idea of moving parts in a device that will be stored for years and expected to work in the worst conditions. The Greatland is just a simple hand held laser that you point at a plane hoping it will shine on the windscreen and they will notice you.
