Eurolight conversion adaptations [dialectric grease]

[Livolsi, Stephane]

My dad, an electrician by trade, educated me on the properties of
di-electric grease. 

In his words, this grease will 'enhance an electrical connection where
there is one, and insulate where there isn't one"

Also, it absolutely should not be used on any electrical contacts that
open and close (such as a switch) because it will increase the amount of
sparking when the switch is opened or closed and shorten it's life.
