Well, yes, I didn't mean that fuses are switches. I didn't really say what I meant to say, I guess. Fuses either are functional or burned through, I thought, but after your reply I guess they could be only occasionally functional if rust/corrosion/poor connection was present in the fuse box. I checked the fuses and they look excellent, as do the headlight connections and the relay lugs/prongs. I'm guessing that the headlight relay has partially given up the ghost OR maybe the bulb failure indicator relay has started to lose its brain. I did manage to find the headlight relay online (http://www.swedishparts.net item number 1362900) , but the list was like $133.00 US and the retail suggestion was $95.00, which I didn't understand. I think a 10 dollar junkyard relay would be best, if I can find one. I'm in Fairbanks, Alaska, and there aren't a lot of cars in the auto wreckers of my make and model, I would guess. After all, I'm not in Portland, Oregon (yet!)
If I can't find a used headlight relay, I guess I'll bite the bullet and buy a new one. Ouch! If that doesn't work, I guess I'll try the bulb failure indicator relay, if I'm reading the Volvo green repair manual correctly. There seems to be a lot of stuff in the headlight circuit: Headlight relay, Power relay 15I, Fasten seat belt reminder, Intermittent relay/windscreen wiper, bulb failure relay, and I only checked the headlight relay for bad connections. I'll have to pull out the related relays and check them, I guess. Complex system, for sure!
Thanks so much for the help, alex, and dmanpdi. I will report back with my findings. I would have thought the headlights would be bullet proof, relatively speaking, and they are stock with no modifications. I used to have E-code headlights in my previous 1989 Volvo 760 sedan, but that was overseas, and it was Euro spec. Lots more horsepower with that engine: yeehaa! Keep on Brickin' and I can't tell you how much I appreciate this community.
