Been there done that, a horrible feeling.
If the rod between the catch and the lock mechanism is still connected even though the lock is loose. 
Forget about the hinges and levering anything.

Remove the driver's side light and drill a 1/8 hole as shown in the pics.
Use the wire to snag the mechanism. It will need to go in about 130 mm.
 
WIDE MR's suggestion could also work too with a longer wire of course.
 
Good luck.

You probably would not be able to without cracking the top of the light.
Why dont you try doing do the same thing but going in with a longer wire through the indicator as someone suggested previously .  If you can use your camera you should be able to see what you are doing.

Woohoo!!  Congrats.
