" How about just putting in an inline fuse holder? "
____ You mean with a fuse that's rated for JUST the minimum amount of amperage required only for just the headlight-circuit*itself ? - (* Instead of only relying on just the stock [over rated] fuse that's supposed to protect the entire lighting-circuit.)
Cuz otherwise, such a proposed remedy would-not provide any significant additional protection for saving the Hi/Low-switch from built-up overheat-damage. _ And besides that,, when a switch-connection has progressed into a heated-connection, it then passes less current, which of-course lessens the strain on the fuse (thus pretty-much assuring that it would provide NO effect) !
__ But lets say the added-fuse was always sure to do it's intended job of saving the switch from ever overheating,, the fuse's current-limit would have-to be of such a low amperage-rating, that it would then be blowing-open on a frustratingly regular basis.
And-also, installation of a relay is really no more difficult than installing a pair of in-line fuses.
" I know that the old CEV switches can fail due to corrosion and moisture on the contacts. "
____ Right ! ... As contrary to pop.belief, it's not the normal current-flow that overheats a (capably suited) switch,, but rather a poor contact-connection that can't pass the amount of current which the circuit demands. _ And-so whenever such a secondary bottle-neck forms at the switch-contacts, that poor-connection then becomes as a 'load' (since it is no-longer preferably acting as a 0-ohm conductor), and therefore must handle wattage which it's unable to adequately disburse without creating an amount of heat that the plastic-parts can't cope with !
" I would take off the cover and spray the switch down with WD40
It survived for a lot of years with that kind of maintenance. "
____ I'm thinking that you would've spent less time & trouble if you had rather installed a 'relay'.
