When I first got my Westy, which is an '81, it had been sitting for a few years.  As part of
the general fixup, I replaced every exterior lightbulb on the vehicle with new ones, even if
the old bulbs were working, and I cleaned out all lenses and got the corrosion out of the
contacts.  As part of this, I replaced the sealed beams (the '81 has just two sealed beam
headlights, one on each side).  I replaced the sealed beams with Sylvania Halogen sealed beams
I got at Wal-mart, adjusted them, and they work great.  I live in the country, so am almost
never on lighted city streets.  These lights work fine.  I think they were $10 or $15 each.
