I always install relays for the lighting.
Head lamps, high beam and low, route through the stalk switch. Toasted those contacts more than one. Last time I replaced the stalk switch I wired in two BOSCH light relays. hardly any amperage to pick the armature. Contacts rated for 20-30 amps. No worries.
Your fog lights are probably going directly through your dash switch. Gets hot, contacts fry. Put in a relay.
Been there, done that. Live and learn. Don't lose your lights at night!
