Thank you all for the suggestions.
All running lights are out - tried wiggling bulbs to no avail. Tail and license out also. Fuse still good - tried another fuse and cleaned contacts on fuse block.
Now I’m thoroughly confused.
Bought their reproduction manual for my '78 FJ40 and the maintenance manual. Both seem to be very similar, if not identical, to the originals. Very inexpensive also - bought them to leave in my on-board tool bag.
Running lights went out yesterday - no big deal, right..... grab a new fuse and swap it out. Wrong - fuse was blown - 15A glass fuse - replaced it no problem. Still no lights. (Headlights and brake lights still work - just no front or rear running lights)
