What's the difference?.....

......between a sunroof, and a moonroof ?

[Sancho]

Is this a follow on from the earlier slightly inaccurate answer - now pretending there's something someone else knows that you don't? Anyway:

"Historically, sunroofs have been opaque and open to the air to allow the sun to shine directly into the vehicle, while moonroofs have generally been transparent or semi-transparent and designed to remain closed while allowing muted light to penetrate the vehicle."

Wikipedia's words, not mine.

Whoopee! I've got a moonroof

[BUSHWHACKER]

Oh, I see, so moonroofs just let in more dark!

Nah. If they're only semi-transparent, they block out more dark to make
it appear lighter.

moonroof

Moon roofs allow the easy tracking of U.F.O's..........the truth is out there!

You open a sunroof during the day And a moonroof at night !!
Seems pretty obvious to me

[Snoop]

If it starts raining and refuses to shut then there would be quite a few other names for it.
