The lenses and reflectors removed.
The hardware holding the brackets to the signals consists of bolts running through the housing and nuts/washers inside. It could be possible to torture yourself and try to get a deep socket wrench into the signal through the wire access hole, but I wasn't gonna try. The sockets are held in place by the same screws holding the reflectors to the middle bracket, and they just fall down otherwise, so I used tape to hold them in place.
