To do this, you have to untwist the two carts (you can see at the open door), and then pull the flashlight back (relative to the movement) and pull the two pistons. If you just can't get it out, you can use a matchbox and a screwdriver. We break the boxes and turn them over. The resulting tool climbs into the crack between the lantern and the body while the carton protects the lantern and the body. The gentle turn of the screwdriver and the lantern is detached.
It may be that the holes in the hull and the spherical reflector will be removed and the lamp will be removed.
