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!

Thanks Ron - any recommendation on what type of relay to use? I have a 4 contact relay for the horn on my Alfa - are they all the same if they have the 4 contacts (85,86,87, 30)? Was planning on jumping 85 and 30 together, connecting the wire from the toggle to 86 and connecting the lights to 87...diagram below:
