all are on the same circuit... that's a good place to re-check. I did do as Ron and George suggested and worked with my tail bulbs and connectors. I found a number of spades that were a bit backed off, but tightening those up did no good. I did not re-check my fuse in daylight But I should have. Losing two sets of light and my horn, especially when the two-stage brake/tail lights half work, makes me think some issue up in the fusebox. Maybe the fuse just needs a twirl to clean the connections... Come to think of it, #1 looked okay but was actually out. Those fuses have been in there for more than 22 years so maybe I should just replace them all to be safe...

I should have checked that today, but I ended up removing my original seat belts and putting in some inertia reel belts, cutting, shaping and installing new floor carpet, making new front seat supports, and removing my generator and installing a bosch unit from my old 1800E. I still need to replace the right steering control arm (it's bent) and wire up the new alternator, but I'll get the fuses checked first thing and let you guys know if it that's what it was...

Thanks!
