UPDATE
Also, I now learn that the power antenna and blower motor died at the
same time the lights stopped working.

Fuse relay maybe?

Hmmmm

Hi, I am a visitor to this forum courtesy of a parent who owns a 1988
Landcruiser.  The headlights will not come on, and when the switch is
turned on, the bright light indicator on the dash comes on (using the
headlight switch will not make it go on or off). Also, both turn
signals on the dash light up and stay lit.  I take this as an
indicator or warning.

The two 15A fuses on the dash are good. I am thinking maybe the switch
on the steering column, but wanted to ask first. I get no lights, dim
or bright.

Thanks!

Jamie

All of the fuse links under the hood look good. The green/white wires
to each side marker light are now disconnected because the lights fell
off. There in one blue/white wire fuse link disconnected by the
battery. Not sure where it goes.

Until you through in the wrinkle of the power antenna and blower motor, I
was going to suggest it was a bad ground at one or both of the headlights.
It may still be the case and you have multiple problems, or a bad common
ground.

When the light fell out, the wire might have shorted which would fry the
fuse link wire that protects the headlight harness from fire.  The
heater blower is likely on this fuse link also.

I don't know where the fuse links are on that machine, but normally they
are on the positive battery cable end.

Fell off? Why? Is this thing a rust bucket or has it been in an
accident?

The failures you mentioned are generally unrelated unless there are some
serious wiring or grounding problems. Time to get out a wiring diagram,
a voltmeter and start running down all the involved circuits.
