Wow Carl, that is one heck of a great improvement!! I bought one of these many years ago, plus an extra genny/pulley set for a lower price than the lamp post set. I really like the added terminals and of course the switch is fun to flick on and off when running with an engine to see the effect a load has.
I was just looking for an engine on the shelf yesterday and flicked the pulley by hand on mine and was surprised how well it lit the bulb.
