Nav Light Out, Captain wants to go. WWYD?

Indeed, there's a switch to go from primary to the backup lights in the breaker panel behind the captain's seat.

That being said, it shouldn't be thrown without MX doing it, and/or MX supervision, and/or making sure it's in the book and MEL'd properly or a crew down the road could be hosed when the backup burns out and nobody knows that somebody flipped the switch.

Or said another way, follow your company guidance on the issue and don't just start mashing buttons and flipping switches on your own.

Precisely! And that's what we did with our late but legal departure.

The CRJ 200 has two bulbs. If one goes out you write it up and they eventually fix it. On the 700 there are two bulbs but only the primary is lit unless it burns out and then the secondary turns on, except for the first 5 (I think?) minutes after you first throw the switch, where they both are on.

As it turns out our (M) procedure "May be flight crew member accomplished." I know because I did it the other day.

A bit older, but our 707's have two lights as well. However, they're both always on. When one burns out, write it up and hopefully replace it before the second one goes.

The 727 is the same way. Two Nav lights on at all times. But it is amazing how a Boeing tap will turn the light on the majority of the time.

My Volvo's position lights are the same way.
