Just from the safety perspective I think they are worthwhile

This is a major point that seems to have been lost in this thread.

I don't do enough night flying to matter, but I DO fly in compressed,
crowded, uncontrolled, airspace. I like to fly with my landing light on for
increased daytime visibility, but they are only good for what? 50 hours? If HID
lamps put out the same amount of light as stock lamps, but lasted indefinitely
so that they could be always left on in flight, the increase in daytime
visibility alone would be worth the price of the upgrade.
