Is the only difference between the RS headlight switch and the standard one the vacuum tubes for the vacuum system? I am in a total rebuild and am going to a DSE system to open and close the headlight assemblies. Do I still need to use a RS headlight switch or can I use a standard one?

you get it seperate..when you order the kit..dse offers there own switch..and you can use the standard switch....

here's a pic..

67 were electric operated 68 & 69 were vacuum operated
