There may be other advantages, such cheaper, smaller, and lighter
circuitry because high voltages aren't required, and a more rugged unit.

For what it is worth; police light bars, for which the best technology
has previously been stobes, are now available using LEDs instead. I haven't
seen them yet, but you have all probably seen LED traffic signals, they do a
great job, even in the brightest Florida sunlight, on a fraction of the
energy of incandescent lights. I hadn't thought of it until just now, but
LEDs may someday have real promise enhancing glider visibility.
