Generally the indicator lights would be lit up maybe once a year for a test, and would be dark up until there's a problem or the next test. Granted, most companies have probably switched to LEDs already if they can, but there are many cases where the LEDs are not compatible with whatever voltage the device is putting out. We've generally gone to LEDs where ever we can. There's still many cases where it just doesn't make any sense whatsoever to go with something other than an incandescent bulb. Are you going to force all those kids with easy-bake ovens to use a CFB when it is completely unsuited for the purpose? I'm sure there are many other lurking problems like that where the legislationwonk never even thought it would be a problem. It falls back to the Wizard's Second Rule about unintended consequences.

How about places where the light is rarely on, and you run into the fire-up costs of a CFB? How about a refrigerator light. Every time you open the door, that CFB has to fire up and warm up and could cost you more than an incandescent bulb. Can CFBs even survive in an oven to use for an oven lamp?
