The hibeam dash indicator is driven off the left-hand high beam circuit. If that's the one that's out, then yes, no hi-beam dash indication.
The headlights have individual fuses in the relay box in the engine compartment. Make sure the fuse is good. Unplug and plug in the fuse, just to make sure it's making good connection.
Try this trick - with the highbeams on, open the engine compartment relay box, and give the relay called "Lamp Control" a light whack with a screwdriver. We're talking firm tap here, not driving nails into hardwood. If that seems to fix it, turn the car off, get yourself some electrical contact cleaner (Radio Shack) and pull out the headlight and Lamp control relays, and spray the crap out of the sockets. Brighten up the relay tabs with some fine sandpaper or Scotchbrite. Just a pass or two - don't take the plating off.
Take a voltmeter and measure the voltage at the headlight fuse. See if it goes up to 12V+ when you engage the highbeams. Try it two ways. First, pull the fuse, and measure both sides of the fuse, highbeams on. The headlight side of the fuse will be zero. The relay side should be 12 volts or more. If not, then the problem is the headlight relay. Now, stick the fuse in, and measure the voltage onthe fuse. The fuse usually has a little gap in the lead where you can stick a meter. If the voltage is now zero, or only a couple of volts, the problem is the headlight relay.
If the problem is the headlight relay, chances are since one side works, it's just a bad contact internal to the relay. You can open up the relay and clean the contact surfaces with a little fine sandpaper.
