BP,

This is not an issue. Off-state dark is preferred especially in homes or automobiles. Because of high energy costs you would not want to have to use power to keep windows dark for privacy. Most want their homes to be darkened when they are out or after they have gone to bed. So the majority of the time you would want dark. Same with automobiles.

But what's important to know for safety regulations is that there are back-up systems. I'm not an expert on all these but REFR is. Contact them.

Here is InspecTech's solution:

Ironically when I was at the Aircraft Interiors show the concern was that the windows were not DARK ENOUGH for privacy. It has to do with the density of the particles in the film. You can have different ranges. The darker the off state the more tint you will have in the clear state. The goal is to make that range as wide as possible. I hear they are working on 5%-95% range. That would probably require the black particle which is currently in the works.

A side note on this issue. This was brought up as an issue during a fire. A fireman laughed at me when I asked about it. Apparently the smoke wipes out any visual field you would have. He said they'd never have a chance if they had to depend on outside lights to fight fires!
