If you don't drive in the fog much, put in some driving lights. I pulled the power lead off the low beam fuse and put it on the high beam, now when I go to high, I get highs and the driving lights(when the switch is on).
Yes, they're a little low to be most effective, but it sure is nice having a mile reflective range when you're doing about 90. I'm using some old Cibie Series 95 driving lights. On my '73 they fit in the standard location and I trimmed an aluminum piece to to give it a nice finished look.
