No low beam. No high beam. Daytime running light only.

I ride a 1992 K75. My headlight is on, but is very low, like a car's daytime running lights. Switching the switch from high to low makes no difference. But… when I flick the switch to temporary high beam (bottom position) the light does go to high beam. I suspect the switch needs to be replaced. Suggestions?

Could be a few things it could be a blown low beam filament, they have a parking light and that could be what you are mistaking for a running light. Could also be a faulty relay or could be a dirty switch. Switches are able to be disassembled and cleaned see the post on the forum, need to be careful lots of small parts and springs do the disassembly over a plastic box it will save a lot of searching. You need to check with a multimeter at the light socket and work your way back, if you don't have a manual with a wiring diagram they are downloadable from this site.

+1 on the switch.  There is a fair amount of electrons going through those contacts.  As things get funky the resistance increases which causes the contacts to heat up which accelerates the whack.  Since there is very little time on the Hi Beam flasher contact, that one stays pretty clean.

I would look at the possibility of cleaning the contacts.  Start out by shooting some Deoxit in there and working the switch a bunch.  If that doesn't get it, you will have to go in there and clean things up manually.  If all that fails, there are a bunch of switches on eBay for reasonable money. 

Before you go much further, get a relay harness from Eastern Beaver.   Not only will it keep you from burning up your handlebar switch, it will make you headlight a bit brighter than when all the electrons were running through the handlebar switch.

Thanks a bunch for the info!
