I’ve done this several times, although my garage door is high enough that - as long as the skylight is only partly open - it passes through. But each time it is a “DOH!” moment.

As I thought of your situation, I think I have a (partial) solution: tie a bit of red ribbon to the skylight armature. Tuck it up into the mechanism. Then, whenever you put the skylight up, flip that ribbon so that it dangles down - in your sight as you back up. 

Maybe not a perfect solution, but it might help…
