Clutch kills the lights

[EyeDontPlay]

Thanks for replying!

ground wire to the radiator?

I've never heard of such a thing.
I ran out and took a peek under the hood to see if I could see anything that looked right.
it just so happens the radiator isn't in the car right now, because awhile back the water pump seized up, the fan sheared off, and went into the radiator, damaging it.
enough to make it leak, but not unrepairable, so it's at the welder's shop now.
the only ground wires I see screw into the frame piece that the upper radiator brackets mount to.
they seem to be individual ground wires for each headlight.
they're both tight and seem sound.

am I looking at the right thing?

am I off in thinking it's something under the dash that the clutch pedal is hitting when moving?

thanks again,
