On / Off Toggle

I remember when I first started design, I always have trouble to come up a good digital representation of on / off switch.... Ok, I still have the trouble. It's really hard to show what's "on" now - you can show "on is pressed in" but is that really feel like it's on?

Today I encounter TV.com's lights on | off button.


First, it has the instant feedback... thanks to Ajax. The page flip between White and Black, with some (bad) delay. Second, doesn't matter what you press, it switches.

It didn't solve the issue from its root, but I felt it's a good recover from users' mistake. ONLY.... with that delay... I toggled many times before I finally landed on the Lights ON stage.
