Re: Headlight dimmer switch/optical horn

& I just had both headlights go out at same time on 93 dakota 5.2L club cab LE.
& Headlights will not come on when push/pull level is pulled out. Running
& lights work fine. If dimmer lever on steering column is pulled back (as if
& to switch from high to low beams) then low beams will come on. As soon as
& lever is released, lights go out. I checked the dimmer switch itself and it
& checks our OK per repair manual. Also tried a new switch with same results.
& Manual describes an "optical horn". Is this some sort of headlight relay?
& If so, does anyone know where it's located? Help appreciated.

Sounds like the switch on the turn signal stalk that turns on the high
beams momentaraly. I never use it-doesn't it operate by pushing the
turn signal stalk back? It may use a remote relay somewhere. Either
the turn signal switch unit or the relay may be bad.
