Dr.Robin,
Thru the years I found the lanterns stay on better if you replace the original high heat bulbs, with low voltage low heat LED's, so that the Lantern cover Tab feet, do not get soft from being over heated, this keeps the tabs stiffer, and the covers stay on the switch better, using both my technique and Guns glue dab technique, the 022 Lantern covers stay on much better. This works for the 711's, 072's and all the old high voltage Lionel switches.
